Computer simulation of flow in packed wire screens of a regenerator is successfully attempted using a technique similar to the boundary element method. One-dimensional potential flow is assumed and the local helium volume increase by heating and pressure change is replaced by source or sink. Finally, fictious sources are attached to both ends, satisfying the given pressure conditions. Darcy's law is applied to obtain flow velocity from potential. This method requires no iterative processes. This fairly efficient calculation is installed in overall crycooler performance calculations, and the change of velocity distribution in the regenerator is successfully investigated in the course of the refrigeration cycle.
