概要 | Modeling the pressure diffusion process is discussed to improve the prediction of turbulent recirculating flows by a second moment closure. Since the recent DNS research of a turbulent recirculating flow suggeted that the pressure diffusion process of the turbulence energy was significant in the recirculating region, the present study focuses on the rapid part of the process consisting of the mean shear. This rapid pressure diffusion model is developed for the Reynolds stress equation using the two component limit turbulence condition and added to a low Reynolds number two-component limit full second moment closure for evaluation. Its effects are discussed through applications of turbulent recirculating flows such as a trailing edge and a back step flows. Encouraging results are obtained though some margins to be improved still remain. |
