Abstract
In this work, an alternative formulation for the specific dissipation rate in the Speziale-Sarkar-Gatski / Launder-Reece-Rodi Reynolds stress model is assessed. Here, g=1/omega) is considered as an alternative for ! and the performance of the g-equation is assessed for a range of test cases, which include validation test cases to flows around industry relevant configurations. Comparison of predictions shows that the predictions are similar to omega predictions and yet demonstrate less dependency on the near-wall grid resolution due to the natural boundary condition at solid walls.
