Geometric parameter optimization of ejector-expansion refrigeration cycle with natural refrigerants

International Journal of Energy Research, 2009
Thermodynamic analyses and comparison of ammonia-, propane- and isobutane-based vapour compression refrigeration cycles are presented in this article using constant area mixing ejector as an expansion device. Optimization of ejector geometric parameter based on the maximum cooling COP and performance improvement for different operating conditions is ...

Magnetocaloric effect of Sr-substituted BaFeO3 in the liquid nitrogen and natural gas temperature regions

AIP Advances, 2017
We have investigated the magnetocaloric effect (MCE) of Ba1-xSrxFe4+O3 (x≤0.2), a series of cubic perovskites showing a field-induced transition from helical antiferromagnetism to ferromagnetism.
