Dr. Drake 1. Solve the diﬀerential equation derived in class to show that the dispersion relation for the Kelvin Helmholtz instability for the ramped velocity proﬁle discussed in class is given by
vm 2 1
+ (kL − )2 − e−4kL = 0
4 (1) 2. Plot the normalized growth rate γL/vm versus kL. Determine the value of kL
that marks the stability boundary. ...
