压气机试验研究的重要目的是发现其内部工作不好的部位,为修改设计提供可靠的依据。由于实际测取参数的位置和数量有限,希望通过实测数据与计算机计算相结合进行详尽的气动分析,从而能够对整个流场作出仔细的判断。 一、基本方法 多级轴流压气机试验存在两种可能的测试方案。除共同测量进口参数(总温、总压、流量)和出口参数(总温、总压、流角)外,第一种测试方案认为只测量中间各级静子后参数
The important purpose of the experimental study of the compressor is to find the parts which are not working well inside, and provide a reliable basis for modifying the design. Due to the limited location and quantity of the actual measured parameters, it is hoped that the detailed aerodynamic analysis can be carried out by combining the measured data with the computer calculation, so that the entire flow field can be carefully judged. First, the basic method There are two possible test scenarios for multi-stage axial compressor test. Except for the common measurement of the inlet parameters (total temperature, total pressure, flow) and outlet parameters (total temperature, total pressure, flow angle)
