Abstract
The operation of self-actuated valves in suction and discharge processes plays
a crucial role in the thermal efficiency and structural reliability of hermetic reciprocating
compressors. The present work provides a thorough description of an in-house numerical method
based on a partitioned fluid-structure interaction algorithm intended to obtain high-fidelity
numerical predictions and optimise valve system design. A large eddy simulation model is used
for the turbulent flow, whereas a normal mode superposition assumption along with an impact
penalty method is used for the reed. Under this framework, a detailed analysis of the coupled
problem with a straight and tapered exit ports is carried out. Differences in effective flow area
and pressure drop are found as a result of the port geometry, but also of the valve velocity
