Unformatted text preview: infinite parallel plates separated by distance h, with both the top plate and bottom plate stationary, and a forced pressure gradient dP / dx driving the flow as illustrated in the figure below. (note that dP / dx is constant and negative ) The flow is two-dimensional in the x-y plane. The velocity components are given by ( 29 2 1 2 dP u y hy v dx =-= where is the fluids viscosity. u Control Volume for b H Control Volume for a 3m ME331 Spring 2009 Homework #2 due: 18.3.2009 11:00 a) Is this flow rotational or irrotational? If it is rotational, calculate the vorticity component in the z direction. Do fluid particles in this flow rotate clockwise or counterclockwise? b) Calculate the linear strain rates in the x and y direction and calculate the shear strain rate c) Is the flow compressible? d) Is the flow steady?...
