Objectives 1. Set up COMSOL to generate steady GWSh solutions for the benchmark Navier-Stokes problem statement of flow in a step-wall diffuser using the DP + DM streamfunction-vorticity formulation. 2. Determine the primary recirculation region reattachment x-coordinate on the lower wall for Reynolds number spanning 100 < Re < 600. Adjust the length of the solution domain, if necessary, to ensure that the outflow BC specification of vanishing normal derivative is appropriate for each Re. 3. Determine the minimum mesh M necessary to generate engineering accurate solutions at Re = 100 and Re = 600. 4.
Compare your GWSh solutions on recirculation region span to the available
experimental data and quantify the observations.
