Mathematical Simulation and Design Optimization of a Novel Swing Vane Compressor

Abstract

Swing vane compressor (SVC) is a novel rotary compressor, which is structurally simple with a small size, a light weight and smooth operation. The SVC also has advantages, such as reduced frictional losses and improved mechanical efficiency at high speed. In this paper, a mathematical model including the geometrical, thermodynamic, flow and input power aspects was formulated, which was then linked to an optimization algorithm to search for three main structural design parameters under three sets of design constraints, for an optimum compressor performance with maximum energy efficiency ratio (EER). In the end, the mathematical simulation of the compressor were given and the theoretical optimization study predicted that a large reduction in frictional loss could be possibly achieved, which brings about an improvement in EER of the compressor of about 8.55%.
