| 摘 要： | 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。

| Abstract: | To study the transfer characteristics of inlet temperature distortion in the compressor.A geometric model of compression system was described.The stage distribution in different faces was obtained through solving the unsteady 3-D Euler equations.A method for calculating inlet temperature distortion was developed.As an example,the efection of the model was verified for a 3-stage compressor.Under the inlet circumferential total temperature distortion,the distribution of total pressure,static pressure,total temperature,static temperature and flow coefficient in different faces was obtained as well as,the response of the 3-stage compressor on total temperature distortion. |
