Lectures On Computational Fluid Dynamics Pdf Turbulence Turbulence whenever turbulence is present in a certain flow it appears to be the dominant over all other flow phenomena. that is why successful modeling of turbulence greatly increases the quality of numerical simulations. Many turbulence models are based upon the boussinesq hypothesis. it was experimentally observed that turbulence decays unless there is shear in isothermal incompressible flows. turbulence was found to increase as the mean rate of deformation increases.
Applied Computational Fluid Dynamics And Turbulence Modeling The function of turbulence modeling is to devise approximations for the unknown correlations in terms of flow properties that are known so that a sufficient number of equations exist. Above the different types of turbulence models have been listed in in creasing order of complexity, ability to model the turbulence, and cost in terms of computational work (cpu time). In order to narrow down the choice of turbulence model in terms of stable converging solutions, each class of turbulence models are to compared among themselves first before comparing all models with the experimental data or dns les. Then, low reynolds number models refer to turbulence models which can simulate the flow in near wall region where the viscous effects dominate, by integrating the equations right to the wall, without resorting to wall functions.
