abrasive particle velocity

基本解釋

The study showed that when length of circular column part is 2.5~3.0 times outlet diameter, abrasive particle velocity near to 95% velocity of water-jet.
研究表明，儅噴嘴的圓柱段長度是噴嘴出口直逕的2 5 ~3 0倍時，粒子的速度能達(dá)到水射流速度的95%。
According to its motion equation formulated, road function was deduced and velocity of abrasive particle in the nozzle was calculated by numerical analysis.
筆者根據(jù)建立的磨料粒子運(yùn)動方程，推導(dǎo)出具有普遍意義的勻速流場內(nèi)粒子路程函數(shù)以及用數(shù)值分析法求解出粒子在噴嘴內(nèi)的速度；
