Friday-Tuesday
FRIDAY
Friday a group of us went to Amsterdam for the weekend. Our train was about 6 and a half hours long and we didn't get in until about 11:30PM. Once we got in, we had a hard time finding our hostel, but we did. I didn't go on any of the other trips with the group I was with but they all said the other hostels were a lot better. It wasn't too bad because we were hardly there, we only needed it to sleep and shower, so it was fine. After we dropped our stuff off in our room, we went out and walked around and got something to eat and just went back to the hostel to get some rest before Saturday.
SATURDAY
Saturday we woke up early and went on the free walking tour of Amsterdam at 11 AM. Before that, we went to a restaurant not to far from the start of the tour and had a good (inexpensive thanfully) breakfast. Nothing big, but it was good enough! We saw a lot of interesting things on the tour but I won't spend much time going into too much detail on them for those people who might possibly visit one day. I'll add pictures at the end and give captions though. After the tour, we went to restaurant and ate dinner. I got a pizza but it wasn't the greatest so afterward, I didn't feel too well. We all went back to the hostel and took a nap, but I wound up actually just going to bed because of my stomach ache. I was going to go out with the rest of them but I was alseep.
SUNDAY
Our train didn't leave until 4:57 on Sunday so we had a good amount of time to do things. However, it was raining so it kind of put a damper on the day. We did walk around but the line to the Anne Frank House was extremely long, even in the rain, and we didn't want to wait and be soaked. Even those these paragraphs are brief summaries of my trip this past weekend, it was fun and interesting to see another country in Europe. I didn't go into much detail because I still have two other days to talk about, as well as pictures. After leaving Amsterdam though, I still have a strong dislike for smoking and Amsterdam just made my dislike stronger, lol.
MONDAY
Monday was my birthday and I spent the majority of it on trains! :D Ok, so of course I was being sarcastic there but even though yes, most of the day was spent on trains, from about it was a nice birthday. We went to Peenemünde which is a village in north Germany and also home of the Nazi rocket center. It took about 4 hours to get there and the tour we went on only lasted about an hour, lol. Some of the things we saw and were told were interesting though. On the way back, some of us split up and went home while others went to a beach. Those of us who went straight home however, got on the wrong train so we basically wound up meeting up with those that went to the beach. We didn't get home until about almost midnight! We had to take two trains to get home but the second train didn't come and the next one wasn't until an hour after that one! After being on the trains aaaallll day basically, I was hungry and tired so I basically just came home and went to bed.
TUESDAY
Today is my brother Justin's birthday! :D He sent me the cutest e-mail wishing me a happy birthday and telling me he can't wait for me to get home! He said I love you about 3 or 4 times too! Anyway, this morning I woke up around 8 and went to H&M and bought a little over the sholder and across the body purse which I've wanted for awhile. It wasn't expensive so that was another good thing! My roommate bought a few things which were kind of expensive though, lol. After leaving H&M we went on a free walking tour of Berlin. It's funny to me that I've been here for over a month and am just now going on the tour. Usually that is one of the first things people do when they go visit big cities like this, but I waited until a week before I'm leaving to go on it, lol. I'm glad however, that I did go on it because even though a lot of the stuff I've already seen or heard about, the tour guide we had gave us a lot of information and history on somethings which was interesting. Later today we're going to a Bunker underground tour. I have exactly a week left in Germany until I come home! ( : I'm excited to go home, but I'm going to miss Germany at the same time. I have a lot of pictures from these past couple of days and it will take too much time to upload them all to this blog so I will post them on facebook and hpoefully you all can check them out! ( : Right now my internet is acting funny so I won't be able to add the rest of the pictures I wanted to, but I will!

First week Technical Report
Coming into this research and lab course, I was not sure what to expect. I have never done any formal research nor do I have as much background knowledge as other members in my group. I am going into my sophomore year and the other members are going into their final year, or have just completed their final year. I have not taken any engineering courses, so I have yet to gain the experience in those courses that could potentially help me with this project. However, lacking the knowledge the other members in my group have does not discourage me; it boosts me to try harder. I enjoy learning from hands-on work, as well as from conversation with the other members of my group. I find our project interesting and look forward to seeing what solutions we can come up with as a group. Our task is to design a fluidized bed gasifier, particularly for wood gasification. More specifically, we are trying to determine ideal dimensions of the gasifier which will allow a sawmill to use the deposits to produce energy. Ideally, the gas produced will power an engine which operates a generator. It is also our task to estimate essential fluidization velocities, the amount of air that is needed to help the gasifier run, and the amount of product gas. Lastly we are asked to determine the power components of the plant.
Upon reading the project tasks, I was unsure of the method that could best accomplish them. One such reason behind my uncertainty is that we are simulating and testing to design something that will be of much greater size and capability. Knowing this makes things a little more difficult, as it does with any smaller scale research project. I do not have much background in reactors or gasifiers, but with the help of my group, we were able to come up with some ideas to help lead us to a solution. By running tests and changing variables, we can determine which combination of things which would most efficiently produce energy. The best way to determine this is by doing individual tests on wood, sand, gasses, and other components of the total system. We will possibly consider pre-heating the air that flows into the reactor, changing the mass of the wood, having a homogenous in flow of air or not, as well as other factors.
So far we have had two days of discussion and brainstorming, and two days of hands-on work. The first day, we determined and drew out systems diagrams representing the flow and components of the plant. We made diagrams of the system as a whole as well as each individual component; feeding, drying, reactor, engine, etc. We also included on these diagrams, mass and energy balances. After having an idea of how the system would work, we ran a few tests the next day in the lab. So far we have conducted tests sampling 1 gram of wood to help us to determine the upper and lower heating values, the amount of ash content after burning wood, and the moisture content after heating the wood. We also have experimented with fluidized bed systems. We changed certain variables such as the volume flow of air, the amount of sand or wood beads in the bed, and the makeup of the sand in the bed. We have yet to change the diameter of the duct which the air flows through, but we will likely conduct this test next week. Thus far, I have a better understanding on what the overall goal of our project is. Although I do not have as much background knowledge in engineering in general, I am looking forward to learning a great amount through this project.
Thursday-Sunday
Thursday
We spent some time simulating different situations with a fluidized bed model. (I will upload my first week report which goes into a little detail, as oppose to me typing it all here) Thursday night we went to Potsdamer Platz to see Transformers 2 which was a GREAT movie. From where we live, it takes about 30 min to get there. For whatever reason, the trains WE needed to take were delayed/shut down so even though we left in time, we wound up getting to the theatre when the movie was supposed to start. After running to the theatre, to our suprise, there was about 30 min or so of previews so we rushed for nothing. After one preview advertising snacks, they even closed the curtains on the screen and movie theatre venders were walking around selling snacks! On the way home, my friend told me about Michael Jackson being rushed to the hospital earlier that day. Unfortunately, once I made it home, I got online and found out he passed. I know everyone dies, but sometimes it's just hard to realize it once that person is no longer there.
Friday
We didn't do any work in the lab on Friday really. Our project advisor just talked to us about our progress so far and what we will be doing these last two weeks. We discussed with him the conversion factors for the pressure drops we recorded when working with the fluidized bed. He also told us it is important for us to look up the composition of pine wood, as well as the combustion equations for those components. Everyone in my group went out of town this weekend so that is one reason why we only doing research for about an hour and half, because they had to catch their trains. I was going to go to Munich with them but I didn't buy a Eurail pass like the rest of them so it would have cost me close to $125 Euros for a weekend trip to another city in Germany. Even though I've heard Munich is great, yet very expensive, I'd rather spend that amount and maybe plus a few more Euros to go to some place out of Germany since I've already visited other cities in Germany. I didn't mind not going because I spent the weekend with my pen pal Vivian! ( :
Saturday
I didn't wake up until very late because Friday night I watched the entire season 3 of "The Game" until about 6 am. Once I did get up though, I went to the mall to buy some more earrings because the ones I had broke. Luckily they were only 4 Euros and for the time being, I can wait until I get home to spend more money on earrings. ( : After leaving the mall, I met up with my pen pal Vivien and we went to her house to get ready to go out for the night. I met her parents as well as her younger brother. They don't speak any English so sometimes when they wouldn't understand me or when I didn't know how to say something in German, Vivien would have to translate it for them. Her mom said she really likes me and wants me to come over more often. We also were talking about when Vivien comes to visit, the language barriar might be difficult with my parents, as it is for me with hers. It's so different because Vivian and her mom speak so quickly it seems to me, when it probably isn't fast at all. Even though she won't be able to come visit me in the states until a summer vacation, I'm really excited and so is she! After getting ready, we went to a disko, as they call it here, called SODA. That place was HUGE! It had several different rooms for everyone's liking. Each room played different kinds of music so there was something for everyone, oldies, R&B/Hip-Hop, techno, etc. It was free for girls until 1 am too! I met some of Vivi's friends who all were impressed with my German! ( : It was a little difficult for me though when they were talking to one another because they'd talk to quickly or use slang words which I wouldn't have learned out of a text book. It was cool though hanging out with people my age, other than people in my program. I really like that place and might go back with people from my program one our weekends here. On the way home, we met these really cool people on the subway but unfortunately, when I was trying to store their number, either I heard them wrong and stored the wrong number, or they gave me the wrong one. I'm not sure which one happened, but I just know after talking the entire subway ride, we didn't decide to exchange numbers until it was time for me to get off. They were yelling the number out as the doors on the subway were trying to close so they were pushing them back open shouting out numbers and saying "Call us now so we have yours!" I don't know what the chances of running into them again would be but hopefully somehow we will, because they were really nice!
Sunday
Didn't do much of anything today but clean and update my blog. The people who went out of town come back today though. I doubt we will do anything tonight because of research tomorrow, but if anything interesting does happen, I'll be sure to blog about it. ( : Like I stated earlier in this blog, I will upload my first week report that was due Friday, for those who are more interested in the research I am doing.
