Performance assessment of engine exhaust-based segmented thermoelectric generators by length ratio optimization

Thermoelectric generators have been regarded as a prospective technique used for recovering engine exhaust heat. Segmented structure is more appropriate for large temperature gradient between the heat and cold source. This work establishes a numerical model of segmented thermoelectric generator for engine waste heat recovery based on the component level and system level simultaneously. Two patterns of p-n ratios are conducted to compare the...
