in this study, the performance of an irreversible regenerative brayton cycle is sought through power maximizations using finite-time thermodynamic concept in finite-size components. optimizations are performed using a genetic algorithm. in order to take into account the finite-time and finite-size concepts in the current problem, a dimensionless mass-flow rate parameter is used to deploy time v...

The performance of a tunnel furnace and dryer in brick production was exergoenvironmentally assessed. real data factory Turkey with daily capacity 392 tons fired bricks were used the analysis. exergoenvironmental factor control volume calculated as 0.87. specific cost determined to be 559.55 €/h, 3.39 €cent/ kg 1.94 €cent/MJ. exergoeconomic environmental damage prevention obtained 0.41 € cent/M...

Biofuels have become a source of renewable energy to offset the use fossil fuels and meet demand for electricity, heat, cooling in industrial sector. This study aims (a) develop simulation trigeneration system based on gas turbine cycle an absorption chiller unit, using biomass syngas from spent coffee grounds (SCGs) replace conventional currently supplying requirements instant plant located Gu...

In this paper, a novel integrated system is proposed to improve the performance of a conventional low-grade geothermal-based organic Rankine cycle (ORC). The main idea is to utilize two TEG units to recover the waste heat of the condenser and geothermal brine. The proposed model is investigated and compared with simple ORC from the energy, exergy, and exergoeconomic viewpoints through the param...

• Complete exergoeconomic optimization of binary power plant that includes cooling tower using variable metric minimization method. The research proposed a cost rate equation for wet and introduced sustainability index (SI) eight different working fluids. This study investigated complete comparison dry-cooled plants. Simple organic Rankine cycles (ORC) Olkaria geothermal field in Kenya isobutan...

This work focused on a compound PV/T waste heat driven ejector-heat pump system for simultaneous data centre cooling and recovery district heating. The uses as the generator’s source, acting with vapour generated in an evaporative condenser ejector drive force. Conventional advanced exergy exergoeconomic analyses are used to determine cause avoidable degree of components’ destruction rate cost ...
