摘　　要：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自然空化形成超空泡形态问题展开研究。分析了水下超高速运动体在不同速度下超空泡形态的变化规律,比较不同速度下空泡脱落计算结果的异同。通过数值模拟,验证了LES数值模拟与试验结果的关系,以及评估非稳态空泡流的计算模拟能力。The supercavity form which is formed by the natural cavitation of the ultra-high-speed underwater moving body was researched by using the method of the combination of theoretical analysis and numerical simulation,which aims to study the motion state of the supercavity form and to compare the similarities and differences of the vacuoles off calculations at different speeds. The relationship between LES simulation and experimental results was verified by using the method of numerical simulations to assess the capacity of numerical simulation of unsteady cavitating flow.
