Modeling Turbulent Boundary Layers with Elliptic Relaxation

The theory behind the RANS equations and common DRSM modeling terms is presented. Most current DRSM turbulence models have models for the redistribution tensor which are developed for homogeneous flow. The Elliptic Relaxation model is presented, which is an attempt to make homogeneous redistribution models behave better close to walls. This model is then implemented in the CBC.RANS framework, which uses the Finite Element Method. Results are analyzed with a focus on stability. Further investigations and improvements are proposed based on successes and failures
