本文提出一种简便的无叶蜗壳设计计算方法。其理论依据建立在理想气体涡流流动等环量规律的基础上。令无叶蜗壳流道各截面形状完全相似,并用吊重法确定截面的重心位置,从而不难建立截面面积和重心距与其某一几何参数之间的简单函数关系,并得到这些函数在流道任意(?)角上的解。本文还认为,作为表征无叶蜗壳技术性能的参数应是F_0/R_0值,而不仅仅是F_0值。
This paper presents a simple non-leaf volute design calculation method. The theoretical basis is based on the law of annular volume of the ideal gas flow. So that the non-leaf volute flow channel cross-sectional shape is completely similar to, and use hanging method to determine the location of the center of gravity of the cross-section, so it is not difficult to establish cross-sectional area and center of gravity and a geometric function of a simple function between the parameters and get these functions in the flow Solution of arbitrary (?) Angle. This paper also argues that the parameter used to characterize the technical performance of the leafless volute should be the F_0 / R_0 value, not just the F_0 value.
