Turbulence stochastic model and its appliction in 3D numerical simulation of flow and sediment
Xinzhou Zhang · Journal of Sediment Research · 2009
Guoren Dou's Turbulence Stochastic Model has been used to establish turbulence model and SIMPLE method has been applied to solve the coupled 3D equations based on hydrodynamic pressure correction method.The influence of velocity in vertical direction to sediment incipient motion has been considered in this paper.The simulation results,experimental results and results based on Boussinesq hypothesis have been compared finally.It has been shown that the simulated results with consideration of Guoren Dou's Turbulence Stochastic Model agree with the measured data very well and are more accurate than other turbulence models.
