摘要
为了保证燃气轮机运行过程中流经进气稳压室的气流应尽量均匀,以免造成压气机的喘振和整个动力装置性能的不稳定,建立三种不同模型,分别对其进行数值模拟,从阻力特性和速度均匀性两方面分析是否影响进气系统的流场。结果表明:速度随进气的推进呈现逐渐增大的趋势。滤器的布置对进气系统的阻力特性有较大影响。
In order to ensure the air flows through the intake plenum chamber as uniform as possible during running process of the gas turbine, and to avoid the instability of compressor surge and the dynamic performance of the device, three kinds of different models were established, and the numerical simulation was carried out. The flow field in the inlet system was analyzed from two aspects of the resistance characteristic and the velocity uniformity. The results show that the velocity increases with the air intake. The arrangement of the filter has a great influence on the resistance characteristic of the intake system.
