Review Paper on Inverted Brayton Cycles

Abstract

The exhaust gas from an internal combustion engine contains approximately 30% of the thermal energy of combustion. Waste heat recovery (WHR) systems aim to reclaim a proportion of this energy in a bottoming thermodynamic cycle to raise the overall system thermal efficiency. One of promising heat recovery approaches is to employ an inverted Brayton cycle (IBC) immediately downstream of the primary cycle. However, it is a little-studied approach as a potential exhaust-gas heat-recovery system, especially when applied to small automotive power-plants.The experiments of the IBC prototype were conducted in the gas stand. The correlated IBC model can be utilized for the further development of the IBC system. Researchers were reviewed core paper on Inverted Brayton Cycles (IBC) and concluded that there were possibility of heat recovery system in that for changing different mechanical components.
