HW #10 Read sections 4.4, 6.3, and Chapter 9. #1 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 the figure below. The flow is steady, incompressible, and two-dimensional in the xy -plane. The velocity field is given by j i h y V v u V ˆ 0 ˆ ) 1 ( ) , ( + = = r . Generate an expression for the stream function, Ψ , as a function of the channel height y. What is the value of Ψ along the top wall? #2 Calculate the volume flow rate per unit depth into the page for problem #1 by a) Integrating the velocity field (integral conservation of mass) b) By using the streamlines at the top and bottom walls
