Summary

Four regenerator compositions comprised of two-layers are experimentally characterized in PM II with an interface temperature sensor. In all the regenerators the warm layer is packed with Gd, while the cold layer consists of different Gd1-xYx alloys. The performance is analyzed assuming a linear temperature profile between the hot, interface and cold side temperature measurements. The linear temperature distribution is used to evaluate the adiabatic temperature change, specific heat and entropy change distributions in each multilayered regenerator. The regenerator with the largest refrigerant capacity (RC’) is found to develop the largest temperature span at each operating condition.
