Two Dimensional Boundary Layer Growth with Suction

Abstract

The boundary layer equations for the unsteady fluid flow with constant suction velocity have been worked out for the impulsive motion of a circular cylinder in the form V(t)=A exp (Ct) where A and C are certain constants. The stream function has been expanded in terms of some functions X/sub 0/(s) where s is a function of y coordinate. The phase angles for various terms have been calculated, and variations shown graphically for large and small frequency of oscillations, where the oscillatory motion is obtained on replacing C by iw.
