Hi all, I'm a ME graduate student concentrating in fluids and I'm trying to decide between two electives. The two I'm looking at are Nonlinear Control Systems or Advanced Heat Transfer. Nonlinear controls looks interesting, but I'm not sure how it could tie in with fluids...as opposed to heat transfer which obviously has its cross-over, but looks much drier. I have yet to take a heat transfer course in graduate school, whereas I did take a nonlinear dynamics class last semester. Any input is appreciated!
