Once again the equation of motion is given by = (4.1-44) du ay? and the initial and boundary conditions are given by at I.C.: att so, V=0 for all y (4.1-45) B.C. 1: at y = 0, for all t> 0 (4.1-46) Ox = v R{etust Vj = 0 B.C. 2: at y = 0, for all t > 0 (4.1-47) 4D.1 Flow near an oscillating wall. Show, by using Laplace transforms, that the complete solu- tion to the problem stated in Eqs. 4.1-44 to 47 is V. VW/2vy =e VO cos (wt - Vw/2vy) e-wt( sin Vw/vy) (4D.1-1)
