An Effective Numerical Simulation Method with Improved Turbulence Model

摘要

Based on the view of nonlinear interacting mechanism, an improvedrngoverning equations is established for modeling the turbulence. Following therndeveloped model, an effective method has been proposed to simulate turbulentrnflows. The objective of the present work is to discuss the improved mechanicalrnmodel and develop the discrete fluid method and applied it to simulate turbulence.rnResults of the simulation shows good agreement with the experimental data for thernbackward-facing step flow problem.
