Abstract

Abstract:

The predictive performance of linear and nonlinear eddy2viscosity turbulence models for homo-geneous shear flow and two transonic flows is presented. Three linear models are: k2E model of Shih &Lumley, CMOTT and SST model.Two nonlinear models are: the quadratic model of Shih, Zhu& Lumleyand the cubic model of Shih, et al.. The benchmark flows are two transonic flows over bump geometrieswith shock-wavePboundary2layer interaction including separation. The computational results demonstratethe superior performance of nonlinear models over the linear models.

Key words: transonic flows, turbulence models, eddy2viscosity
