不同叶型叶片扩压器对离心压缩机性能影响的数值模拟
Numerical Investigation on the Influence of Different Vane Type Diffusers on the Performance of Centrifugal Compressor
摘要
Abstract
Diffusers with different types of blades impose very different influences on a centrifugal compressor.Four different vane diffusers are simulated at first,and their flow fields including flow velocities,pressure distributions as well as the comparison of their diffusion effects are investigated. Then the numerical simulations are conducted on centrifugal compressors consisting of these four different vane diffusers,and the overall influence of these four different vane diffusers imposed on the performance of the centrifugal compressor are analyzed comprehensively,drawing to a conclusion that the centrifugal compressor composed of aerofoil blade embodies best performance.关键词
