The research paper mainly deals with waste heat recovery from internal combustion engines (ICE) using the organic Rankine cycle (ORC) and Thermoelectric generator (TEG). Simultaneously recovering the wasted heat of both exhaust gases and coolant, a novel configuration named two-stage is proposed. Then a comprehensive thermo-economic analysis and optimization are conducted. Produced power and total cost rate are selected as the objective function of the optimization. Also, the first and second stage pressures of the ORC system are considered as decision variables. Finally, a sensitivity analysis is performed to study the effect of expander inlet temperature, pumps isentropic efficiency, and expander isentropic efficiency on the objective function.
这篇研究论文主要探讨了利用有机朗肯循环（ORC）和热电发生器（TEG）从内燃机（ICE）中回收余热。本文提出了一种名为两级的新型配置，可同时回收废气和冷却剂的废热。然后进行了全面的热经济分析和优化。选择产生的功率和总成本率作为优化的目标函数。此外，还考虑了 ORC 系统的第一级和第二级压力作为决策变量。最后，进行了敏感性分析，以研究膨胀机进口温度、泵绝热效率和膨胀机绝热效率对目标函数的影响。
