CFL number specification sonic/supersonic flow
 
Is there criteria for picking a cfl number for a sonic/supersonic flow? What is the effect of choosing a cfl number too big or small for the same grids? Is there are an optimum value? I would appreciate any thoughts or references on this.

Thanks in advance gr
