水下超高速运动体人工通气流动过程研究

Artificial Ventilation Cavity on Super High-speed Underwater Vehicle

采用理论分析和数值模拟相结合的方法,对水下超高速运动体人工通气超空泡形态问题展开研究;旨在研究水下超高速运动体在不同的通气流量下的运动状态和空泡内压力的变化规律,比较不同的多相流模型对相同情况的计算结果的异同;通过数值模拟,得出了2种多相流模型的通气质量流率与通气空泡形态之间的关系。

In this paper,through the combination of theoretical analysis and numerical simulation,re-search about the artificial ventilation cavity morphology of super high-speed underwater is made.The aim of this paper is to study the motion state and super cavity internal pressure of underwater super high-speed vehicle at different ventilation flow and compare the same situation with different multiphase flow model to calculate similarities and differences.Through numerical simulations,the relationship between the mass flow rate and ventilation cavity morphology between the two models of multiphase flow.
