Abstract

The regenerator is one of the crucial component of cryocooler. Pressure drop across the regenerator is one of the parameter which determines the performance of the cryocooler. Thus, effect of average pressure on porous medium hydrodynamic closure on steady axial and radial flow for different mesh sizes, different material is considered in this paper. In this paper, the first section shows the work done on regenerator for steady flow, both for axial and radial direction. The second section highlights the complexity of flow in porous media and thus the need of more tedious oscillatory flow. The permeability and Forchheimer inertial coefficient which defines the momentum loss of the porous media is obtained using repetitive iteration using CFD assisted method. The same parameters are also determined for the Oscillatory flow through regenerator, have been discussed, and comparison for steady and oscillatory flow is made.
