为了研究进气总温畸变在压气机中的传递特性,建立了压缩系统的几何模型,通过求解非稳态三维欧拉控制方程,计算了气流参数在压气机各截面的分布,获得了一种计算进气总温畸变的方法。以某三级压气机为例,对模型的有效性进行了验证。在进口存在周向总温畸变的情况下,计算得到了总压、静压、总温、静温和流量系数在各截面上的分布规律,得出了该三级压气机对总温畸变的响应。
In order to study the transfer characteristic of total temperature distortion in the compressor, a geometric model of the compression system is established. By solving the Euler governing equations in unsteady state, the distribution of the gas flow parameters in each section of the compressor is calculated, and a Calculation method of total temperature distortion of intake air. Taking a three-stage compressor as an example, the validity of the model is verified. The total pressure, static pressure, total temperature, static temperature and flow coefficient in each section of the distribution under the circumstance of total temperature distortion exist in the inlet, the response of the three-stage compressor to the total temperature distortion is obtained .
