Abstract
The VM refrigerator with power being supplied by liquid nitrogen shows great potential for application below 10K. The 2D axisymmetric model refers to actual geometry under oscillating flow conditions is carried out using FLUENT software. The lowest temperature, the pressure in three cavities, the temperature profile along the regenerator is presented. The simulation results show good agreement with available data. Then the regenerator between cold and middle cavity is optimized to obtain the lowest temperature, it is filled with stainless steel screens and lead shot. It is found that there exists an optimal ratio of stainless steel screens and lead in the same length regenerator.
