Thermodynamic, economic, and environmental analysis and multi-objective optimization of a dual loop organic Rankine cycle for CNG engine waste heat recovery

Waste heat energy exists in the exhaust, intercooler, and coolant during the operation of the compressed natural gas (CNG) engine. The cascade utilization of the waste heat energy of the CNG engine can be realized considering the structural advantages of the dual loop organic Rankine cycle (DORC) system. Operating parameters have an important influence on DORC system performance. Traditional analysis methods have limitations in analyzing the...
