Performance analysis of a high-efficiency multi-bed active magnetic regenerator device
M. Masche, Jierong Liang, Stefano DallʹOlio, Kurt Engelbrecht, Christian Robert Haffenden Bahl
Izvirni znanstveni članek
Oznake: magnetocaloric effect;cooling performance;active magnetic regenerators;first-order phase transition;
We present the performance of an active magnetic regenerator prototype with a multi-bed concept and parallel flow circuit. The prototype applies a two-pole permanent magnet (maximum magnetic flux density of 1.44 T) that rotates over 13 tapered regenerator beds mounted on a laminated iron yoke ring. ...

Effects of surface finish and mechanical training on Ni-Ti sheets for elastocaloric cooling
Kurt Engelbrecht, Jaka Tušek, Simone Sanna, Dan Eriksen, Oleg V. Mishin, Christian Robert Haffenden Bahl, Nini Pryds
Izvirni znanstveni članek
Oznake: elastocaloric effect;surface finish;colling;fatigue life;shape memory material;
Elastocaloric cooling has emerged as a promising alternative to vapor compression in recent years. Although the technology has the potential to be more e ffi cient than current technologies, there are many technical challenges that must be overcome to realize devices with high performance and accept ...

CFD-simulation assisted design of elastocaloric regenerator geometry
Kristina Navickaite, Michael Penzel, Christian Robert Haffenden Bahl, Kurt Engelbrecht, Jaka Tušek, André Martin, Mike Zinecker, Andreas Schubert
Izvirni znanstveni članek
Oznake: elastokalorično hlajenje;računalniška dinamika tekočin;regenerator;termo-hidravlične lastnosti;elastocaloric cooling;computational fluid dynamics;thermo-hydraulic properties;
Elastocaloric cooling is a promising alternative to conventional cooling using the vapour compression cycle, with potentially higher theoretical exergy efficiency. Nevertheless, there is a number of challenges to be tackled before the technology can be commercially available world-wide. In this stud ...
