The present work considers the development of a computational model to simulate the dynamics of reed typevalves of reciprocating compressors. Because the valve dynamics and the time dependent flow field through thevalve are coupled, they are solved simultaneously. A one-degree of freedom model is adopted for the valve motionand the finite volume methodology is employed to obtain the flow field through the valve, which is assumedincompressible, turbulent and axisymmetric. In view of the valve motion a numerical technique has been developedto take into account the variation with time of the computation domain. Through a coordinate transformation amoving coordinate system is obtained so as to expand and contract according to the valve displacement. Results forthe turbulent flow (streamlines and turbulence intensity) and for the reed motion (resultant force, valve lift andpressure distribution on the reed surface) are obtained for a prescribed periodic mass flow rate at the valve entrance.
