Abstract

A one-equation turbulence model is formulated which retains an anisotropic eddy viscosity coefficient. Consequently, the current model is deemed to be potential for accounting near-wall turbulence and strong flow in-homogeneity, enhancing the predictive accuracy for complex separated and reattaching flows. Furthermore, the devised turbulence model retrieves the link to the k-ε model and is likely to be extendable toward a non-linear algebraic Reynold stress model. Intuitively, the current artifact may accommodate a variable eddy-viscosity coefficient for an LES (large eddy simulation) or a DES (Detached eddy simulation) method.
