Experimental research was carried on a three-stage low-speed axial compressor with different inlet distortion. 本文对一台带有不同周向进口畸变装置的三级、低速、轴流压气机进行实验研究。
The post-stall behaviors, such as surge and rotating stall, of a three-stage compressor are simulated based on an one-dimensional unsteady model for the dynamic response of compression system. The variations of the annular average parameters, i. e. 基于描述轴流压气机及其系统的动态气动响应的一维非定常数学模型,通过数值求解,即可对系统的过失速过程进行数值模拟。
This paper presents a numerical simulation of the first stage in a three-stage low-speed axial compressor by solving two-dimensional incompressible N-S equations. 本文通过求解二维不可压N-S方程,对某三级低速轴流压气机的第一级进行数值模拟。
Based on the dynamic static pressure variations, a new criterion and a recognition method of aerodynamic stability in multistage compressors with inlet dynamic distortions are developed. The predictions for a three-stage axial compressor with dynamic temperature, dynamic pressure and their combined distortions are given. 应用新准则分别对进口动态温度、动态压力及动态动力&温度组合畸变下的多级轴流压缩系统的气动稳定性进行了预测分析。
