Although CFD has been widely applied to the study of positive displacement compressors, the primary challenge remains in the generation of solution domain of complicated geometry and accurate handling of the deformation of the working chamber during the compressor operation. In this paper, a 2D transient CFD simulation employing the overset mesh method is performed on the Coupled Vane Compressor (CVC) with air as the working fluid. Initial results revealed the presences of flow reversal and circulation zones at the suction channel resulting in the reduction of effective suction flow area. This has significantly reduced the mass intake. Proposed modification to the suction channel design has resulted in an increase of mass flow rate of 6.97% when operating at 1500rpm. Simulation approach, results and design modification are presented and discussed in this paper.
