Abstract
Thermoelectric modules (TEMs) embedded in heat exchangers provide a means of converting industrial waste heat into electrical power for local electrical energy needs. Due to the nature of the thermoelectric effect, a generator's efficiency is dictated by a balance in its ability to act as a heat exchanger and its ability to maintain a high temperature difference. The present system-level study investigates the thermal conditions required for optimal power generation when using TEM embedded heat exchangers. From the analytical results, optimal thermal operating conditions are scrutinized, and a model is developed providing insight into the balance between heat transfer and temperature differential for optimal thermoelectric generator (TEG) design. It is demonstrated that under constant temperature difference, a heat exchanger effectiveness of 0.5 is an optimal compromise between heat flux and temperature difference for thermoelectric power generation. This criterion is universally applicable to TEGs as it relies solely on basic heat transfer and thermoelectric equations. Numerical simulations confirm that constant temperature difference along the length of the generator is achievable using tabulated inserts. A generator's efficiency and power output are analytically solved and compared to the experimental results.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
