Nasa backward facing step
WitrynaThe performance of the Spalart Allmaras turbulence model was found to be consistent with previously published results for flow over a backward facing step (NASA 2015). The K-ω model appears to perform the best out of the three, predicting the reattachment and pressure distribution most accurately. AcuSolve demonstrates the ability to predict ...
