【摘要】 利用任意拉格朗日 欧拉(ALE)方法,通过直接对N S方程进行数值求解,对柴油机直圆形、圆缺形、缩扩形等几种孔式喷油嘴内流体流动过程及质量流量和喷嘴特性参数进行数值计算,计算结果有助于柴油机喷油嘴的设计。更多还原

【Abstract】 In this paper ,ALE technique is used to simulate fluid flow in several type injection nozzle of diesel engine. The simulation on the flow in injection nozzle gives the flux coefficients and resistance coefficients of it .The results is valuable for the design of the injection nozzle of diesel engine.更多还原
