Abstract:

k-ε model and two-scale turbulence model are studied and theirs modification are made in this paper. The models are applied to four hypersonic copmlex flows consisting of two cuses of a 2-D compression corner, an ogive-cylinder-flare flow, and an oblique shock wave/turbulent boundary-layer interaction. Computational results were compared with experimental data. It is shown that modificadons made to the model resulted in improved predictions of skin friction, surface heat transfer for separated flows.

Key words: turbulence models, CFD, hypersonic flows
