Abstract

The roots compressor is applied widely in chemical industry as well as aerospace industry. In the article, a new combination roots compressor rotor profile curve was designed, internal flow field in three blade straight and twisted roots compressor are simulated. The results show that twisted blade roots compressor has the lower pulsation than the straight one. And the higher the speed of rotor is, the greater the compressor exhaust gas mass flow will be, but the more obvious the pulsation of the exhaust gas flow is. From the situation of the flow pulsation, the speed of the roots compressor shall not exceed 3000rpm.
