An Effective Numerical Simulation Method with Improved Turbulence Model

摘要

Based on the view of nonlinear interacting mechanism, an improved governing equations is established for modeling the turbulence. Following the developed model, an effective method has been proposed to simulate turbulent flows. The objective of the present work is to discuss the improved mechanical model and develop the discrete fluid method and applied it to simulate turbulence. Results of the simulation shows good agreement with the experimental data for the backward-facing step flow problem.
