3.3 Consider two infinite parallel plates, a distance of 0.3 cm apart. The upper plate is stationary and the lower plate oscillates according to u(0,t) = = cos(1000t) = cos(1000nAt) where n represents the computational time level, selected to be 1 at t = 0.0. The governing equation is obtained from the Navier-Stokes equation as = Ju = V J²u at მყ2 Assume the kinematic viscosity is constant and has a value of 0.000217 m²/s, and uo 40 m/s. Select 31 equally spaced grid points with j = 1 located at the lower plate. A time step of At = 0.00002 sec. is specified. Use the FTCS explicit scheme to obtain the solution within the domain up to t = 0.00632 sec. Print the solution for all spatial locations at time levels of 0.0, 0.00158, 0.00316, 0.00474, and 0.00632 seconds. Plot the velocity profiles at the time levels indicated above.
