| Abstract: | An improved numerical method for the high temperature regenerator of a GM refrigerator to simulate its dynamic process and performance has been developed.A variety of factors,such as variable properties of regenerator materials and helium,existence of helium in a void space of a regenerator and so on,were taken into account in the model.It can predict the distributions of temperature and mass flow respectively with time in the regenerator and so on.Some analyses are made to study the effects of structure and operation parameters on the regenerator performance in detail.The predicted values by computer agree well with experimental results.The numerical method can give useful information to design a high efficiency regenerator. |
