Time-marching throughflow analysis of multistage axial compressors based on a novel inviscid blade force model

Abstract: A time-marching throughflow method for the off-design performance analysis of axial compressors is described. The method is based on the Euler equations, and a new inviscid blade force model is proposed in order to achieve desired flow deflection. The flow discontinuity problems at the leading and trailing edges are tackled by automatic correction of blade mean surface using cubic spline interpolation. Empirical loss models have been integrated into the throughflow model in order to simulate the viscous force … Show more

“…The model was verified based on experimental studies of a transonic axial stage and a three-stage P&W 3S1 compressor. The work [10] presents the concept of the through flow method. In recent decades, the through flow method has become one of the most important tools for designers -a compromise between the accuracy of the flow field representation and the corresponding computational cost.…”

“…The authors present the results of verification of their model for two axial compressors. The work [11] presents the concept of the through flow method. In recent decades, the through flow method has become one of the most important tools for designers -a compromise between the accuracy of the flow field representation and the corresponding computational cost.…”

“…This situation usually happens in high rotational speed regions, where SLC has a higher prediction error with the experiment as shown. Some alternative methods are developed to solve this problem, such as the implementation of dedicated models for the choke regions, localized choked flow treatment [39], or time marching through-flow method [40], which is out of the scope of this article. For the comparison of the different models, treatment of this defect is not taken into consideration in this work.…”
