Laminar Couette Flow with Imposed Pressure Gradient
In this application, AcuSolve is used to simulate the viscous flow of water between a moving and a stationary plate with an imposed pressure gradient. AcuSolve results are compared with analytical results described in White (1991). The close agreement of AcuSolve results with analytical results validates the ability of AcuSolve to model cases with imposed pressure gradients.
