This study deals with a cascade organic Rankine cycle driven by linear Fresnel solar collector as a source and cold energy of LNG to produce power. An exergy concept is used to model the system and the performance of the ...

Nowadays, with the population growth, renewable energies- especially solar energy- have grown effectively among governments. These types of energies are considered to be unlimited sources of energy and have the least harmful ...

In this paper, numerical simulation of perovskite solar cells (PSCs) for two structures (direct and inverted) and two perovskites (MAPbX‌‌‌3, MA: CH3NH3, X: I, Br) had been done by SCAPS software. Thickness of active layers ...

This study embraces a steady numerical simulation of thermodynamic model optimized for an ammonia-water diffusion absorption refrigeration (DAR) cycle with hydrogen or helium as the auxiliary gas. A DAR cycle has been ...

Agriculture is a main part to global warming through greenhouse gases because of activities such as deforestation, soil treatment and methane emissions from livestock. It is also one of the main users of fossil fuels; it ...
