Résumé

A two-dimensional differential methodology is developed to simulate the whole operating cycle of a small refrigeration reciprocating compressor, accounting for the in-cylinder flow. Such compressors adopt automatic valves in which the flow dictates the pressure distribution on the reed surface and, consequently, affects its dynamics. Here, the time-dependent flow field through the discharge valve and its dynamics are coupled and solved simultaneously. A one-degree of freedom model is adopted for the valve motion and a finite volume methodology is employed to solve the compressible turbulent flow that prevails in the cylinder and through the valve. Results for the flow field, reed dynamics and indicator diagram are presented to demonstrate the capability of the model.
