Relativel ~ ~ matlab language is more powerful than oilier computing language , especially in computation fluid mechanics , it helps to simply draw charts of vortex , stream function , velocity , pressure , and the amount of work can be extremely reduced , and the program coniplving can also be controlled easily 得到空化數的分布以后,進而分析流場內空泡的運動軌跡,最后得到空泡半徑在流場內隨壓力的變化關系曲線,以及在流場內空泡半徑沿壓力最小點的分布規律。
