TALK=T;RUN(1,1) DISPLAY This case concerns plane, two-dimensional, incompressible flow through a 180 degree turnaround duct. The flow exhibits large streamline curvature together with flow separation near the bend exit next to the inner surface of the duct. Calculations are made with the high-re k-e model and the high-Re 2-scale k-e model. The latter is selected by setting TSKE=T in the Q1 file. The fine-mesh calculation employs a non- uniform mesh of NY=25 and NZ=80, for which the solution is not as yet grid independent. For speed of computation, this library case has been set up to run for 20 sweeps only on a coarse mesh of NY=20 by NZ=40. About 400 sweeps are required for complete convergence.
