Used Matlab to draw the flow rate-△p curves,and analysing the data of the lowest pressure from the simulation results,we get the relations among the flow rate change, angle,opening and△p,and the lowest pressure in flow field:when reducing opening and angle,the flow rate reduce greatly;when reducing opening and angle,the lowest pressure will increase,it is difficult to cavitate.
用Matlab绘制流量-压差曲线,以及通过分析流场最低压力数据,得出了节流孔压差、角度、开度与流量变化(刚度),以及流场最低压力之间的关系:减小开度和角度,流量会大幅度减小;开度和角度越小,流场产生的最低压力越大,越不容易产生负压。
