Internal Combustion Engine Exhaust Waste Heat Recovery Using Thermoelectric Generator Heat Exchanger

Research on Engine Exhaust Energy Recovery by a Heat Pipe Exchanger with a Semiconductor Thermoelectric Generator

A heat pipe exchanger was adopted to recover the engine exhaust energy and its internal gas pressure. Velocity and temperature distribution were obtained with the computational fluid dynamics software called ‘FLUENT’. Based on the simulation results, the structure of the exchanger was improved, and its working performance was verified by experiments. The experiments showed that the pressure los...

Increasing waste heat recovery from an internal combustion engine by a dual-loop non-organic Rankine Cycle

This research proposes the combination of a dual-loop non-organic Rankine cycle (DNORC) with an internal combustion engine to increase the output power of the recovery system by focusing on the increase in the energy input and system efficiency. In doing so, it investigates the strategy of increasing the mean effective temperature of heat addition in the high-temperature Rankine cycle (HTRC) (t...
