Numerical simulation and experimental research on the aerodynamic performance of a gas turbine compressor
To accurately predict the aerodynamic performance of compressors used in gas turbines,particularly under the frequently encountered startup and shutdown conditions that deviate from the design point in actual operations,a two-dimensional streamline curvature method is adopted to simulate and analyze the aerodynamic performance of compressor components at various rotational speeds.The results are then compared with those obtained from experimental tests conducted on a subsonic two-stage compressor test rig that is specifically set up.The results indicate that the two-dimensional streamline curvature method is highly proficient in predicting the aerodynamic attributes of subsonic two-stage compressors in gas turbines.The relative error between the prediction results and experimental data remains within 4.5％,indicating that this method can provide valuable insights for the design and optimization of compressors.
