Abstract
Numerical simulation of three-dimensional turbulent flow in a multistage axial compressor blade row is conducted. A high resolution, third-order ENN scheme is adopted to catch the shockwave and simulate the turbulent flow correctly, while an LU-SGS implicit method is chosen to improve computation rate. A detailed and highly efficient numerical simulation system is thus constructed. The investigation is focused on the grid connecting methods between the rotor and the stator and the corresponding treatment of rotor-stator interactional surface. The final results of a three-stage axial compressor with inlet guide vanes conform well to the experimental data.
