Default Different turbulent models!
Posts: n/a
Hello everyone, When I use fluent to simulate 3D flow field in compressor, I find the streamline distribution on the suction surface exhibit differently if I employ different turbulent model(the k-epsilon Standard model, RNG model and Realizable model). In the results of the last two models, the streamline distribution deteriorate and don¡¯t accord with the actual status. What¡¯s the reason? And what should I do? Thank you!
