本文基于实验结果,提出了一种预测轴流压气机叶栅端壁附面层叶片力亏损的通用模型.该模型的理论性强、物理意义明确.它包含了目前广泛使用的现有诸种叶片力亏损模型且明显减少了模型的经验性.应用于不同轴流压气机叶栅端壁附面层流动的数值分析结果与实验结果的比较表明,本文所建立的新模型通用性更强且精度也得到了进一步的提高.
In this paper, based on the experimental results, a general model for predicting the blade force loss in the axial wall of an axial flow compressor cascade is proposed. The theoretical and physical meaning of this model is clear. It includes the existing widely used Blade force loss model and significantly reduce the model’s experience.The numerical analysis results of the laminar flow applied to the endwalls of different axial compressor cascades and the experimental results show that the new model established in this paper is more universal The accuracy has also been further improved.
