Hello,in ansys fluent's dacuments it has been said that : (( ANSYS Fluent has taken steps to offer more advanced wall formulations, which
allow a consistent mesh refinement without a deterioration of the results. Such -independent formulations are the default for all omega-equation-based turbulence models. For the epsilon-equation-based models, the Menter-Lechner and Enhanced Wall Treatment (EWT) serve the same purpose. A -insensitive wall treatment is also the default for the Spalart-Allmaras model and allows you to run this model independent of the near-wall resolution. )) so, is it true that for models mentioned above like k-omega or k-epsilon(EWT,Menter-lechner)there is no need to check y+ value to be in a certain range ? for example can i use k-epsilon model with enhanced wall treatment and y+ value changes between 0.5 to 600 ? if my assumption is'nt true , what is the certain range of y+ value for all turbulence models like k-epsilon with wall functions or k-omega without wall functions ? please give me a reliable source ... thanks |
