Résumé

In this paper, a full 3D transient computational fluid dynamics (CFD) model for a rolling piston compressor with reed valve is described in detail. In the proposed model, a moving/deforming mesh algorithm was developed for the fluid pockets of the compressor. The bending of the reed valve is modeled as a rotational structure with a moving/deforming mesh for the affected fluid volume. The motion of the valve is solved using a one dimensional rotational ordinary differential equation (ODE). Important parameters of the rotational dynamics, such as the torsion constant, are derived from bending cantilever beam theory. The meshing and re-meshing algorithms for the fluid volumes of rolling piston and the rotational valve were implemented in a CFD package PumpLinx. The test simulation of a generic rolling compressor with a discharger reed valve demonstrates that the algorithms and the implementations are robust, fast and user friendly, and can be readily applied to rolling piston compressor systems.
