I wasn’t going to blog so soon after that last one, but today was an awesome lecture day, despite my first prof being annoyed that none of us were participating and my second prof being flustered about having her notes mixed up. It was awesome because the material that I’m learning in the two classes I had today (150A – Intermediate Fluid Dynamics and 105D – Transport Phenomena) matched up almost perfectly. In fact, I really turned to Yuko during 105D and said, “Mechanical engineering is awesome!” during class. So just to share my (almost sudden) amazing appreciation for the concentration, here are pages from my notes from today!
This is from 105D! We just started a new topic today, convection, and it’s really crazily similar to fluid dynamics. Because the way that convection (conduction + advection) works is through bulk motion, which is generally caused by the flow of some fluid or other mass.
This is from 150A! Actually these are my notes from last week, but today we just went into deriving formulas so there weren’t any cool diagrams. Look at the velocity profile in the middle! It’s exactly (almost) the same as the one from 105D! Also, check out that airfoil. It’s SO REAL.
In 150A today we basically derived the definition of viscosity (via the viscous stress tensor) and in 105D we’re doing other things like temperature/concentration gradients and stuff, but they’re both talking about the same thing. They’re both just solving the boundary layer conditions between the surface of an object and a free stream. I love how applicable these things are. It’s fantastic.
Okay, that’s all. I’m done nerding it up, now it’s time for my third nap of the day. (I am sick and I have a midterm on Wednesday. I’m cutting three classes tomorrow to sleep and study, woot.) Oh yeah and sorry that the photo quality sucks, but I was really excited to blog today, haha.
