262 8. Stability and Transition

Problems

8-1. Compute the eigenvalues a r and u on the lower branch of the neutral
stability curve for Blasius flow at 700 < R < 3000. Take u e = 160fts~\ v =
2
1.6 x 10 _ 4 ft s _ 1 . Use BLP to calculate the velocity profiles.

8-2. Repeat Problem 8-1 for m = -0.01 and -0.005.

8-3. Calculate the location of transition for n = 9 for the above two problems
and discuss the effect of pressure gradient on the results.
