本文介绍了一种新的轴流多级压气机通流分析方法。该方法是基于流函数方法和有限元求解程序。它包括一个高保真度的损失和偏差模型与改进的相关性和端壁边界层计算。采用径向损失分布模型和新的展向掺混模型模拟三维流动效应。模型的校准是通过计算具有不同配置的多个测试用例来进行的，其目的是为所考虑的每个测试用例实现高精度和最佳鲁棒性。将该程序应用于某新型燃气涡轮机压气机的流动分析和性能预测。在不同的操作条件下，压气机的整体性能和一些参数的预测结果和测量的测试数据的比较显示出良好的一致性。验证的结果证实，这种方法的基础上校准的相关性可以应用作为一个可靠的工具，在设计阶段的广泛的压缩机配置的流量分析和参数变化。
Abstract This article describes the development of a new through flow method for the analysis of axial multi-stage compressors. The method is based on a stream function approach and a finite-element solution procedure. It includes a high-fidelity loss and deviation model with improved correlations and end-wall boundary layer calculation. A radial distribution model of losses and a new spanwise mixing model are applied to simulate three-dimensional flow effects. The calibration of the models is made by calculating a number of test cases with different configurations with the aim of achieving high accuracy and optimum robustness for each of the test cases considered. The code was applied to flow analysis and performance prediction of a newly developed gas turbine compressor. Comparison of the predicted results and measured test data for the overall compressor performance and a number of parameters under different operating conditions showed good agreement. The results of the validation confirm that this method based on cali-brated correlations can be applied as a reliable tool for flow analysis and parameter variation during the design phase for a wide range of compressor configurations.
