摘要
本文在前文[1]、[2]基础上研究亚音速气体喷射器的理论计算问题。从优化条件导出最佳截面比,利用自由射流束长度取极值条件并联系流控端口特性的方程确定其几何尺寸。文中还讨论了给出的计算公式适用范围及应用效果。
On the basis of psper, this paper studies forther problem of theoretical computation of the subsonic air ejector. The optimum of sectional ratio is derived from optimal conditions. According to Maximum conditions of free jet length and equation of fluidic port charcteristics of the ejector we could determine its geometrical size. The paper discuses the using range and application effect of the computing for mulation.
