The system performance of the supercritical CO2 Brayton cycle for Sodium Fast Reactor with a partial-cooling layout was studied, and an economic analysis carried out. energetic, exergetic, exergoeconomic analyses are presented, optimized results were compared recompression cycle. sensitivity conducted by considering variations in pressure ratios inlet temperatures main compressor turbine. exerg...

The thermal management of modern aircraft has become more challenging as aircraft capabilities have increased. The use of thermally resistant composite skins and the desired for low observability, reduced ram inlet size and number, has reduced the ability to transfer heat generated by the aircraft to the environment. As the ability to remove heat from modern aircraft has decreased, the heat loa...

Energy consumption based on the building heating, ventilation, and air-conditioning (HVAC) systems is sharply rising daily. At this point, heat recovery ventilation save energy while contributing to indoor air quality thermal comfort. This work mainly focuses designing air-to-air cross-flow exchanger system duct lines. First, ducts, bends, vents, unit are placed around selected domain complying...

Abstract This study presents the experimental monitoring of heat transfer performance metal foams in transient state. Micro gas turbines require a compact recuperator with high effectiveness to achieve higher thermal efficiency. Porous media such as and ceramic are characterised by surface-to-volume ratio. They known increase potentially can be incorporated recuperators. Their structure is idea...

Improving the efficiency and flexibility of fossil-fired power plants remains a current challenging issue. In that regard, supercritical CO2 Brayton cycles offer promising potential. This paper aims to apply process synthesis approach design closed cycle using as working fluid with coal furnace heat source. The general methodology presented here for designing includes construction superstructur...

The propulsion demands of high-speed naval vessels often rely on gas turbines, producing significant amount power achieving thus high performance requirements. Gas turbines can be used either to provide purely mechanical propulsion, or alternatively generate electricity, which is subsequently by electric drives propel the ship. However, thermal efficiencies are lower than those Diesel engines s...

Recovery of the low-temperature waste heat for electricity generation has been gaining a significant interest. An Inverted Brayton Cycle (IBC) is often employed to convert waste-heat while thermal efficiency and specific work output are poor. In this paper, new energy recovery scheme introduced incorporating IBC with Regenerative Heat Mass Exchanger (RHME). The RHME mass exchanger that consolid...

In this work, an evaluation and quantification of the impact using mixtures based on supercritical carbon dioxide “s-CO2” (s-CO2/COS, s-CO2/H2S, s-CO2/NH3, s-CO2/SO2) are made as a working fluid in simple complex recompression Brayton s-CO2 power cycle configurations that have pressure drops their components. These cycles coupled with solar thermal plant parabolic-trough collector (PTC) technol...
