MAE 150A, Winter 2007 J. D. Eldredge Homework 7 (5 problems + 1 OPTIONAL), due Friday, March 6 1. Use Thwaites’ equation to compute θ ( x ) for a zero-pressure gradient ﬂow over a ﬂat plate. Com- pare this result to the Blasius solution. 2. Consider the decelerating external velocity given by U ( x ) = U 0 (1 - x 2 /L 2 ). Use Thwaites’ method to predict the location x s /L at which separation will occur. The relationship you get will be messy (a large-degree polynomial). You can use graphical means to solve it, for example.
