The strain-dependent coefficient C-mu assists the SST model in constructing the functions such as to benefit complex flows with non-equilibrium turbulence, while retaining the predictive quality of unmodified SST closure. Naturally, the proposed methods allow the original SST model to be modified ...
寄于厚望的k-omega&SST模型 作为流传最广以及变种最多的湍流模型,k-epsilon 模型的家族成员迄今为止仍然活跃在各大CFD软件之中。不过爱折腾的人类怎能放过展示自己的机会呢,为了改善k-epsilon 模型在求解逆压梯度的流动中的计算精度问题,众多学者做了很多尝试。其中1988年,CFD...
RNG k-e model can be used for a wide variety of flow regimes. SST k-omega, which is a blend between regular k-omega and k-e, can also be accurately applied for a wide range of Re. Having said that, since you are working with a heat transfer problem, it is extremely important to...

Numerical Analysis of Heat transfer in Aeroengine Turbine Blade using k-epsilon and k-omega SST model 来自 ResearchGate 喜欢 0 阅读量: 49 作者:CR Patil,D Dandotiya,B Pal,N Banker 摘要: Even the smallest part engineered in gas turbines adds on hugely to its output performance. The blades ...
The method is based on the numerical solution of the Navier-Stokes equations employing the k - w-SST turbulence model. An existing surface-roughness method, developed for the traditional k — w models, was found to not work well with the SST-model. In this work, the SST-model is ...
In the calculation of flows around aircraft and aerodynamic bodies, the Shear-Stress Transport (SST) model by Menter has been used extensively due to its good prediction of flows with adverse pressure gradients. One main drawback of this model is the need to calculate the distance from the wal...
