Abstract

Two-dimensional unsteady aerodynamic interaction in rotor and stator blade rows are analyzed by using a new numerical method based on multi-block technique suggested by authors. The calculations were carried out for the transonic stage of blade cascades in a steam turbine unit, typical unsteady flow field and unsteady load of blades were obtained. It's found that the numerical approach suggested has the ability to simulate the complex unsteady flow phenomena in turbomachines and the code developed based on it can provide reasonable and acceptable results. Many useful information were obtained from FFT analysis of unsteady load of blades.
