Energy and Exergy Analysis of Two Configurations Rankin Organic Cycle in Heat Recovery of Internal Combustion Engine Heat
Rising fuel prices and limited fossil fuels have motivated scientists to find some new methods to recover the heat dissipation from the internal combustion engines exhaust gases in recent decades. Only 30 percent of the fuel energy is converted to the useful work and the rest of it is lost through the exhaust gases of the engine and the engine coolant system. In this paper this issue has been considered and hence two different configurations of organic Rankine cycle with two operating fluids R113 and R123 have been designed and energy and exergy analysis have been applied in order to recovering the heat dissipation from the six cylinder internal combustion engine exhaust gases (in full load operating mode). Next, the performance of these cycles has been optimized by sensitivity analysis to find the optimum working temperature and pressure of these two cycles. the results shows the optimum points of the system which is calculated by the mention technique.
