Study of CFD Considering Valve Behavior in Reciprocating Compressor

Abstract

It is necessary to understand the behavior of the gas flows in the compression chamber generated by the driven piston, and the behavior of the reed valve that are opened and shut by the fluid force, when we reduce the loss of suction and discharge of the reciprocating compressor. To understand the above phenomenon, the moving object such as piston and reed valves is analyzed by applying virtual flux method and Cartesian grid that is suitable for expressing complex shape as main grid in this study. In this paper, first, we introduce our numerical analysis method. Next, we introduce the verification by the comparison result between the above-mentioned analysis and the experiment.
