【摘要】 认识并掌握水射流产生推进力的机理,是进行水射流切削系统和水射流推进系统设计的基础。本文对几种不同出口直径和锥角的锥形喷嘴水射流反推力进行了理论分析和仿真计算,研究了压力、流量和锥形喷嘴的结构参数对反推力及反推力系数的影响,从而确定锥形喷嘴的最佳结构参数。更多还原

【Abstract】 To get a full understanding of the reaction thrust generated by water jet is the preliminary step that has to be taken before the designs of water jet cutting systems and jet propulsion systems.Simulation and theoretical analysis were conducted to investigate the reverse thrust of water jet through several conical nozzles with different outlet diameters and conical angles.Effects of pressure,flow rate,structure parameters of the nozzles on the reverse thrust and the reverse thrust coefficient were the focus of this research.And the best structure parameter of the simulated conical nozzles was achieved.更多还原
