| 英文摘要 | Accurate prediction of unsteady separated turbulent flows remains one of the toughest tasks and a practical challenge for turbulence modeling. in this paper, a 2d flow past a circular cylinder at reynolds number 3,900 is numerically investigated by using the technique of unsteady rans (urans). some typical linear and nonlinear eddy viscosity turbulence models (levm and nlevm) and a quadratic explicit algebraic stress model (easm) are evaluated. numerical results have shown that a high-performance cubic nlevm, such as cls, are superior to the others in simulating turbulent separated flows with unsteady vortex shedding. |
