ABSTRACT:
In this presentation, a relatively new turbulence model named Gao-Yong turbulence model is investigated using the open source software—OpenFOAM. A newly developed statistical partial average scheme is presented. As the ensemble average is taken on two groups of turbulent fluctuations separately, the partial average scheme able to capture the first-order statistical moment of the fluctuation field, providing valuable information in addition to what have been known in the past from the conventional Reynolds average. Without any empirical coefficients, the derived equations can be used to simulate statistical mean behaviors and coherent structures of various benchmark turbulent flows. The simulated results are in good agreement with experimental data.
