AN ADAPTIVE FINITE-ELEMENT SCHEME FOR TURBULENT FREE SHEAR FLOWS

This paper presents an adaptive finite element method for solving inco mpressible turbulent flows using the k-epsilon model of turbulence, So lutions are obtained in primitive variables using a highly accurate qu adratic finite element on unstructured grids. Turbulence is modeled us ing the k-epsilon model. A projection error estimator is presented tha t takes into account the relative importance of the errors in velocity , pressure, turbulence variables and eddy viscosity. The methodology i s verified by solving problems with known analytical solutions. The me thod is then applied to turbulent free shear flows and predictions are compared to experiment.
