圆形Orbal氧化沟流场三维数值模拟

hree dimensional k –ε turbulence mathematical model was used to simulate the flow field of rounded Orbal oxidation ditch ,and moving mesh technology was used to simulate the power sources of plate running in the ditch.By comparison on the theoretical calculation data and test result ,it was indicated that the result of mathematic simulation is reasonable. Furthermore , detailed analysis was made on the flow pattern in the ditch ,and then the measures of optimization and improvement were proposed for current design from the view of hydrodynamics.
