ON THE IMPULSIVE MOTION OF A FLAT PLATE IN A VISCOUS FLUID. II

Abstract

The manner in which the variable x, measuring distance from the leading edge, first enters into the solution of the title problem is elucidated. The structure of the corresponding eigenfunctions is different in each of four regions of the boundary layer and the corresponding contribution to the velocity is weaker than any finite power of −x+Ut, where t measures time and the variable x t enters at x = Ut. A comparison between the predicted variations of displacement thickness and of the skin friction with the computed values obtained by Dennis (2) is favourable.
