Résumé

This paper proposes an approach to optimizing the efficiency of rotary elastocaloric machines, which is experimentally verified and investigated using CFD simulations. The cooling performance losses caused by fluid mixing are reduced by airflow separation between warm and cold side of the fluid channels in a tension-based elastocaloric machine with inner volume and fluid recirculation. The fluid mixing takes place in previously introduced rotary elastocaloric machines since cooling and heating of superelastic SMA wires takes place in different portions of the same channel. Instead of using additionally actuated locks for airflow division it's preferrable to separate the airflow between cooling and heating portions by means of stationary channel walls of an optimized shape. This design helps to profit from the great potential of elastocaloric effect for the development of emission free, environmentally friendly solid-state heating and cooling machines.
