Numerical Simulation Analysis Of Underwater Supercavitation For Different Types Of Warhead And Cavitation Device

Supercavitation drag reduction technology can make the bullet in the water when running resistance is reduced to 1/10 of the original,the bullet has a higher speed in the water,far distance,has important significance for the new generation of underwater combat bullets.In this paper,three different shape of the bullet and cavitation of numerical simulation of supercavitation formation using fluid analysis software,analysis in different depth and different speeds of the supercavity shape and drag coefficient,in order to improve the performance of the projectile under water.The main contents of this paper are as follows:Firstly,the generation of cavitation,cavitation and numerical calculation of supercavitation are introduced.Secondly,on the tip of the warhead warhead warhead,blunt peace supercavitation is simulated by using fluid analysis software,three kinds of warhead under water pressure contours,velocity contours and supercavity shape,get the resistance coefficient of different warheads.Again,analysis software analyzes emptybubbles reduce three cavitation resistance for warhead using fluid,three kinds of cavitators under water pressure contours,velocity contours and supercavity shape,get the resistance coefficients of three kinds of cavitation,cavitation bubble generated three degree of difficulty.Finally,the drag coefficients of three kinds of cavitating motion at different speeds are analyzed,and the range of three kinds of cavitating projectiles is compared.
