摘要:

文章对筒底结构经过适当的简化,选取了计算模型,给出入口边界条件和筒内流场湍流参数,确立了动网 格边界条件,通过仿真计算,得出筒底压力场。比较筒内特征点压强和试验值之间的吻合情况,从而验证了筒底压 力场仿真方法的正确性。

Abstract:

The simulation model was established through the proper simplification of the cylinder bottom structure. The in.let boundary condition and turbulent parameters of the flow-field were discussed, and dynamic mesh technology was usedin the model. The pressure field was obtained through the simulation. The pressure of the typical position in the simulationwas in accordance with the testing value, and it showed that the method of the simulation was correct.
