摘要
采用欧拉多相流模型模拟均匀来流绕圆盘、圆锥形空化器流动时所引发的自然空化现象,将数值模拟结果与实验、经验公式计算结果进行对比,确认欧拉多相流模型的有效性,数值结果与实验、经验公式结果吻合度高,证明考虑相间作用力的欧拉多相流模型能够较好地模拟空化现象。
The Eulerian multiphase flow model is utilized to simulate the natural cavitation flow of plate cavitator,conical cavitator in free stream by using Fluent software.The validity of this model is confirmed by comparing the numerical results with the ones of experiments and empirical equations.Simulation results are identical to experimental and empirical data,showing that reasonable results can be received with Eulerian multiphase model integrated with interaction between phases.
