摘要: In this paper, a new variant of the k-e turbulence model (Saqr et al., CFD Letters, 1(2) pp. 87–94) is used to compute shear driven vortex flow in an open cylindrical cavity. The results are compared with published LDA measurements for such configuration. modified demonstrated good agreement experimental results, which further supports its validity computing dominated flows.
