The calculation starts at x = -4h and terminates at x = 16h, where a fixed-pressure boundary condition is applied. The Reynolds number based on the step height is 45,000 and uniform profiles of u, k and e are specified at the inlet to the calculation domain. The density ratio of the fluids is 100:1 . ---------------------------------north wall-------------------- Constant prescribed mass inflow rate ----------------> ___________________ ////////////////| Exit step /| Recirculation /| <---- -----> /|_______________south wall_____________________ ENDDIS ************************************************************ Group 1.
