Pouria Ahmadi,Seyed Hosein Torabi,Hadi Afsaneh,Yousef Sadegheih,Hadi Ganjehsarabi,Mehdi Ashjaee +5 more
TL;DR: In this article, a realistic simulation of hydrogen fuel cell vehicles and the development of a lifecycle assessment (LCA) tool to calculate and compare the environmental impacts of fuel cell passenger vehicles with conventional vehicles with the results showed that fuel cell degradation undesirably affected the average fuel economy of the vehicle for about 23%.
Journal ArticleDOI
Convective heat transfer characteristics of magnetite nanofluid under the influence of constant and alternating magnetic field
TL;DR: In this paper, the effects of constant and alternating magnetic field on the laminar forced convective heat transfer of water based magnetite (Fe3O4) ferrofluid in a heated tube are studied experimentally.
Journal ArticleDOI
A novel hybrid thermal management for Li-ion batteries using phase change materials embedded in copper foams combined with forced-air convection
TL;DR: In this paper, a thermal management system (TMS) was introduced for pouch lithium-ion battery (LIB) modules with a focus on stressful conditions, which exhibits excellent thermal performance for the battery pack, especially for a longer working time at an appropriate temperature range.
Journal ArticleDOI
Energy, exergy and exergoeconomic (3E) analyses and multi-objective optimization of a solar and geothermal based integrated energy system
TL;DR: In this paper, a complete renewable energy source based on a solar and a geothermal system is proposed to produce desired electricity and cooling, which consists of a concentrated PVT, a double-effect LiBr-H2O absorption chiller and a Geothermal unit.
Journal ArticleDOI
Multi-objective optimization of a hybrid biomass-based SOFC/GT/double effect absorption chiller/RO desalination system with CO2 recycle
TL;DR: In this paper, a biomass-based solid oxide fuel cell integrated with a gas turbine, a reverse osmosis desalination unit, and double-effect absorption chiller is proposed for power generation, cooling and fresh water production.
