Computational Method in the Throughflow Simulation of Aeroengine Compressor

Tao, Qitian / Jin, Hailiang / Liu, Xiaohua

The computational method in throughflow simulation is investigated in this paper. The present investigation reported the current research status and compared the advantages and disadvantages between different computational models including streamline curvature method, matrix method and throughflow calculation based on time marching. For the most commonly used time marching method, we discussed one key issue in application in engineering reality which is called as the simulation of blade force, which was divided into two categories according to whether to solve the circumferentially momentum equation as master equation or not. In conclusion, compared with other methods, time marching method has more advantages in transonic flow adaptability, shock capture ability and calculating accuracy, so that it has more potentials and prospects in the future research. The blade force model, as a key link in the time marching method, has developed rapidly. However, there is still no unified highprecision model and the modeling of blade force needs more study. With further development, this method is expected to become a standard tool during the aeroengine compressor design stage.
