Use when you must compute the exact unsteady laminar Stokes layer of an infinite plate in a quiescent fluid, either impulsively started or oscillating in its own plane: for the stokes-first-problem Rayleigh layer of a plate started at speed U, evaluate the similarity profile u/U = erfc(y/(2*sqrt(nu*t))), the layer edge at 3.64*sqrt(nu*t) where u/U = 0.01, the wall shear decaying as 1/sqrt(t) from rho*U*sqrt(nu/(pi*t)), and the displacement thickness; for the stokes-second-problem oscillating-plate-layer at omega, evaluate the exponential-cosine velocity field, the penetration depth sqrt(2*nu/omega) with exp(-1) amplitude and 1-rad lag, and the wall shear amplitude rho*U*s…
