单级径流涡轮已在许多领域中得到应用。在小型燃气轮和在增压器中特别适宜采用轴向排气的径流涡轮设计。纯径流式的涡轮特别适宜于各种不同化工工艺设备中应用。在上述各种类型设备的方案设计中必须计算涡轮的主要尺寸并且校核在给定条件下涡轮是否设计成高效率的。为此目的推广了上述两种涡轮的主要尺寸的计算方法。所列举的计算方法简化了繁重的计算并且缩短了在计算涡轮主要尺寸时所花费的时间。1.工质和计算中的假设a)设计一个高效率的径向涡轮可以选择气流径向地进入叶轮和叶轮出口的气流切向分
Single-stage radial turbines have been used in many fields. Radial turbine designs that are particularly suitable for use in small gas turbines and in axial turbochargers. Pure-flow turbine is particularly suitable for a variety of different chemical process equipment applications. The main dimensions of the turbine must be calculated in the design of the various types of equipment described above and the turbine is checked for high efficiency under given conditions. To this end, the calculation of the main dimensions of the above two kinds of turbines is generalized. The enumerated calculation method simplifies the heavy calculation and shortens the time it takes to calculate the main dimensions of the turbine. 1. Assumptions in Working Fluid and Computation a) Designing an Efficient Radial Turbine The tangential gas flow may be selected to flow radially into the impeller and impeller outlets
