ABSTRACT
The regenerator used in Stirling cryocoolers is the crucial component, which has a flow conduit through the porous matrix material. Various parameters affect the performance of the regenerator, of which pressure drop is the main parameter needs detailed analysis. Theoretical analysis of pressure drop across the length of Stirling cryocooler regenerator has been carried out at various mass flow rates (ranging from 0.4 g/s to 1.2 g/s) and at various charge pressures (ranging from 18 to 24 bar), using ANSYS 16.0 Computational Fluid Dynamics (CFD) and REGEN 3.3 numerical program for Regenerators. The paper mainly focuses on the pressure drop analysis of porous cryocooler regenerator in evaluating the optimized porosity value for the regenerator.
