A Study of Suction Check Valve Inner Flow of A Compressor for Automobile Air Conditioner

摘要

An analysis system is developed and studied about the unsteady inner flow. Navier-Strokes Equation is applied for the flow and Spring-Mass model equation is used for the check valve movement. It can be called Fluid-Structure coupled analysis. The time constant, which is handled as the new evaluation item for the suction valve performance, is calculated on the parameter with the design configuration or the valve mass. It is shown that the suggested numerical model is useful to determine the valve design model.
