Abstract

The lag model proposed by Olsen and Coakley1 is incorporated into the baseline two-equation k-ω turbulence model to simulate the transonic and supersonic turbulent separated flow. The performances of the lagged k-ω turbulence model is assessed by computing two transonic airfoil flow cases, the RAE2822 Case 10 and the 18% thick double circular arc airfoil, and a separated nozzle flow. The computational results show that for the flow cases with strong separation, the implementation of the lag model improves the results; while for the attached flow cases, the influence of the lag model is not significant.
