但在湍流粘度计算等方面有差异。其湍流粘度引入限制器,可有效改善BSL模型对涡粘度的过高估计,其定义如下...
BSL模型 标准的k-ω 模型对于自由流非常的敏感,但是在近壁面区的计算中十分的准确。而k- \varepsilon 模型在远离壁面的湍流充分发展区却十分的使用,因此BSL将两者通过混合系数结合,在近壁面区激活k-ω 模型而在湍流充分发展区使用 k-\varepsilon 模型。除此之外,BSL与标准模型的不同还有BSL模型中加入了 (a...
The models considered are the original k-omega model of Wilcox and the BSL model of Menter. A short description of the individual models are given, and the necessary boundary conditions are discussed. The implemented models are tested using two different flow cases. The fully developed channel ...
BSL k-w A variant of the standard k–ω model. Combines the original Wilcox k-wmodel for use near walls and the standard k–ε model away from walls using a blending function. This eliminates the standard k-wmodel’s strong sensitivity to free stream conditions without sacrificing near-wall...
It is based on the BSL model, but has the additional ability to account for the transport of the principal shear stress in adverse pressure gradient boundary-layers. The model is based on Bradshaw's assumption that the principal shear stress is proportional to the turbulent kinetic energy, ...
