From the elastocaloric effect towards an efficient thermodynamic cycle
Parham Kabirifar, Jonas Trojer, Miha Brojan, Jaka Tušek
Izvirni znanstveni članek
Oznake: elastocaloric effect;shape memory alloys;thermodynamic cycle;Carnot;Brayton;efficiency;
In recent years, the elastocaloric cooling technology has been considered as one of the most promising alternatives to the vapor compression technology. Given that the elastocaloric technology is only in the early stage of development, a uniform method for evaluating the elastocaloric effect has not ...

Elastocaloric cooling
Parham Kabirifar, Andrej Žerovnik, Žiga Ahčin, Luka Porenta, Miha Brojan, Jaka Tušek
Izvirni znanstveni članek
Oznake: elastocaloric effect;cooling;active elastocaloric regenerators;fatigue life;driver mechanism;
The elastocaloric cooling, utilizing latent heat associated with martensitic transformation in shape-memory alloys, is being considered in the recent years as one of the most promising alternatives to vapour compression cooling technology. It can be more efficient and completely harmless to the envi ...

Elastocaloric cooling is emerging as one of the most promising alternatives to vapor-compression cooling technology. It is based on the elastocaloric effect (eCE) of shape memory alloys (SMAs), which occurs due to a stress-induced martensitic transformation (superelasticity). In recent years, severa ...
