【Abstract】 The optimal structure and mathematical model of two-stages restrictorvithout cavitation are given by the orthogonal tests、range analysis and regression calculationof the computer. The influence of the various parameters on the critical pressure ratio istudied and the design method of two-stages restrictor without cavitation is also explored.更多还原
