Transmission and Reflection on Pressure Waves by Compressor and Turbine Stages, Based on an Actuator-Disk Model

Abstract

The amplitudes of the pressure waves transmitted and reflected by an actuator disk due to the impingement of an incident pressure wave calculated. Analytic expressions for the wave amplitudes are derived for the limit where the incident pressure rise is small and these formulas, as well as direct calculations, are used to estimate the effect of multiple wave reflections from a pair of actuator disks. These predictions help to explain a number of phenomena that have been observed in measurements made when shock-tube generated overpressure waves were sent into an operating engine. Pressure waves, Actuator disk model, Compressor stages, Turbine stages.
