摘要
为了反映激光切割辅助喷嘴各项参数对气体流场的影响,在边界条件和初始条件相同的情况下,改变收缩角与稳定段长度,通过fluent进行数值模拟,找出最有利于切割加工的参数情况。
To reflect the nozzle＇s parameters influencing the flow of gases,through numerical simulation by use of fluent,this paper mainly find the optimal parameters for cutting processing based on different initial conditions,different terms of the border,indifferent shrink angle and the length of stable line.
