In this article, a nonlinear LRN/DES turbulence model is proposed by introducing Reynolds stress and scale resolution simulation methods to address the contradiction between computational cost accuracy of existing models in wind buffeting noise simulations. After verifying feasibility backward-facing step flow, carried out based on simple cavity model. By comparing with several commonly used experimental results, it found that simulates frequency sound pressure level most accurately, capture flow field also closest result.
