Models of two-stage serial and parallel thermoelectric generators have been established in this paper. Low-temperature thermoelectric material bismuth telluride and medium-temperature skutterudite are employed in the models and the exhaust gas of internal combustion engine is used as heat...

The paper analyzes the combined TEG-ORC (thermoelectric generator and organic rankine cycle) used in exhaust heat recovery of ICE (internal combustion engine) theoretically. A theoretical model is proposed to calculate the optimal parameters of the bottoming cycle based on thermodynamic theory...

An Organic Rankine Cycle (ORC) system used in the Internal Combustion Engine (ICE) exhaust heat recovery was proposed and techno-economically analyzed based on various working fluids. It is significant to recover ICE exhaust heat (about one third of energy generated from the fuel) by ORC system....

A Multi-Approach Evaluation System (MA-ES) is established in this paper providing comprehensive evaluations on Organic Rankine Cycles (ORC) used for waste heat utilization. The MA-ES covers three main aspects of typical ORC performance: basic evaluations of energy distribution and system...

Study on recovering waste heat of engine exhaust gas using organic Rankine cycle (ORC) has continuously increased in recent years. However, it is difficult to find out appropriate working fluids to match with exhaust gas waste heat due to high temperature. In this work, several tentative...

A technical method of recovering exhaust heat in internal combustion engine (ICE) is the thermoelectric generator (TEG), which contributes to efficiency improvement. In this study, a two-stage thermoelectric model is built using the exhaust gas of ICE as heat source. After comparing the single-...

This paper presents a simulation model based on an actual Organic Rankine Cycle (ORC) bottoming system of a diesel engine. The ORC system is built to recover waste heat both from engine exhaust gas and jacket water using R245fa as working fluid. Simulations and thermodynamic analyses are...

A novel dual-loop organic Rankine cycle (DORC) is proposed in this study, which consists a high-temperature (HT) loop and a low-temperature (LT) loop to recover the waste heat of the exhaust, engine coolant and residual heat of the HT loop. Net output power, utilization rate of engine coolant,...

Different types of waste heat recovery technologies available onboard ships have been discussed from the perspective of technical principle and application feasibility. Study of basic principle, novel methods, existing designs, theoretical and experimental analyses, economics and feasibility are...

Effects of lubricant oil additive on the characterization of particles from a four-cylinder turbocharged diesel engine were investigated. Neat diesel and blended fuel containing oil pour point depressant (PPD) additive were chosen as the test fuels. Effects of different fuels on size...
