Description
Summary:The predictions of several turbulence models are compared with experimental data for flows containing regions of recirculation using an inverse finite-difference method to solve the boundary layer equations. A new turbulence model which employs a one-dimensional transport equation for the outer layer length scale is seen to provide the best agreement with experimental measurements beyond separation. Use of the solution of a modeled form of the turbulence kinetic energy equation to supply a turbulence velocity scale in models resulted in no noticeable improvement in predictions over models which utilized purely algebraic and mean flow quantities to obtain this velocity scale.
