Abstract
[Objectives]This paper aims to research the effects of the temperature and compressibility of li-quid water on the super-cavitation phenomenon of an ultra-high-speed underwater vehicle and its motion char-acteristics.[Methods]First,based on CFD general software Fluent 19.2,the free motion of transonic and supersonic vehicles is computed using a numerical model that considers both the compressibility and temperat-ure of the water.Qualitative and quantitative comparisons with the experimental results of reference[1]are made,and the effectiveness of the numerical method is verified.The motion characteristics at different initial speeds are then analyzed using the range at the sailing time of 0.008 s as the comparison base.Finally,the in-fluence of the launch depth and environment temperature on the motion characteristics is discussed.[Results]It is found that when the speed is greater than 2 000 m/s,increasing the initial speed does not sig-nificantly increase the effective range;the critical speed is found between 1 450 m/s and 1 475 m/s,where the range variation is less than 3%with or without the influence of the temperature;as the launch depth increases,the resistance of the vehicle becomes greater and the sailing range gradually decreases;and the higher the en-vironment temperature,the shorter the effective range.[Conclusions]It is shown that the numerical model proposed herein,which considers both the temperature and compressibility of liquid water,can provide valu-able references for the motion analysis of ultra high-speed underwater vehicles and corresponding practical ap-plications.关键词
