Consider fully developed Couette flow—flow between two infinite parallel plates separated by distance h, with the top plate moving and the bottom plate stationary as illustrated in Fig. The flow is steady, incompressible, and wo-dimensional in the xy-plane. The velocity field is given by V-› = (u, ?) = (Vy/h) i-› + 0 j-›. Generate an expression for stream function ? along the vertical dashed line in Fig. For convenience, let ? = 0 along the bottom wall of the channel.calculate the volume flow rate per unit width into the page of Fig. from first principles (integration of the velocity field). Compare your result to that obtained directly from the stream function. Discuss.
