Turbulence modeling is a key issue in most CFD simulations. Virtually all engineering applications are turbulent and hence require a turbulence model. Classes of turbulence models RANS-based models Linear eddy-viscosity models Algebraic models
By its nature, i.e., creating a mathematical model that approximates the physical behavior of turbulent flows, far less precision has been achieved in turbulence modeling. This text addresses the problem of selecting/devising such models. The fundamental premise is, in the spirit of G. I. ...
In the present paper, a profound investigation of the performance of several k-ε turbulence models variants in various CFD applications is carried out. Three k-ε based turbulence models are considered, namely; the standard k-ε model, the υ2-f model and the non-linear k-ε model. The ...
