摘要：

A simple method for pump and compressor performance evaluation is presented. This method only requires a knowledge of the geometry of the machine. Generally speaking, the pressure/mass flow characteristic and the efficiency are computed. The torque is derived by using Euler's equation. Losses taken into account are due to friction, flow separation, off design angles of attack and to leakage between rotor and stator. In the case of a radial turbine, operated at high temperature, evaluation of the performance can be deduced from measurements obtained with cold flow operation.
