4. Given two infinitely wide parallel horizontal plates that are moving at different velocities at a space of H between the plates. The top plate is moving faster than the bottom plate. The flow is fully developed and laminar with no driving pressure gradient. Determine: A) an equation for the velocity as a function of depth B) an equation for the average velocity C) the flow rate per unit width U2 T H I U Note: while this seems like a non-physical problem, it mimics the pattern of a double rotating bearing with the outside rotation faster than the inner rotation. Also, it may simplify your calcs by defining Uz- Uz as AU H 5. Discussion: Which of the following forward difference, backward difference and central difference, is most accurate and why? Why do we need a mesh independence test in a CFD simulation?
