Abstract

A two-layer k-epsilon model is employed for 3D flow computation. Various measures are adopted to ensure stable and convergent numerical solution. A three-dimensional transonic channel flow with multiple shock/boundary layer interactions is studied using the two-layer model and numerical methods. The results are compared with experimental measurements and numerical results obtained by using a Low-Reynolds-Number (LRN) k-epsilon model. Compared with other (LRN) two-equation models, the two-layer model implemented is promising in modeling very complex 3D internal flows in terms of efficiency, robustness and accuracy. The two-layer model permits uniform distribution of flow properties to be specified as initial condition which makes the simulation easier to be carried out.
