In this work, a novel Carnot battery system comprising chemical heat storage/pump (CHS/P) and Brayton cycle is presented. The reversible reactions selected for are the dehydration of calcium hydroxide hydration oxide. re-conversion reaction into electricity provided by cycle, in which working fluid supercritical carbon dioxide (sCO2). This Battery compared to storage two-tank molten salt sensib...

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 present study focused on the analysis of a new geometrical modification conventional zig-zag channel for Printed Circuit Heat Exchangers. research was carried out using OpenFOAM and Salome software, which were used CFD construction computational domain. For development study, three types geometries defined: modified channel, straight channel. results show that achieves better thermal hydrau...

In this study, first-law, second-law, and exergo-economic investigations are accomplished to recover the waste heat of a two-shaft turbofan engine applying supercritical carbon dioxide Brayton cycle. The efficacy different operating parameters including inlet temperature turbine, pressure ratio compressor, Mach number on performance proposed system in terms energy exergy performance, destructio...
