Numeric Analysis on inside Flow Field of Roots Compressor

Abstract:

The roots compressor is a kind of rotary compressors, it is applied widely in mechanical engineering, chemical industry, aerospace industry and other fields with its high speed, long life and mechanical efficiency. In the article, a new combination rotor profile curve of the roots compressor was designed by reviewing the relevant literatures, the 2D finite element modal was established and a transient CFD numerical simulation was performed for a roots compressor by means of dynamic mesh technique. The varying tendency of mass flow rate, the velocity vector and static pressure distribution of the roots compressor were obtained and analyzed.
