Investigation of a Thermoelectric Generator with Sandwich Leg Modification

Renewable energyEnergy awareness is increasing due to the large demand for energyEnergy. Thermoelectric is a renewable energyEnergy source. Thermoelectric performance is an interesting research area. This article presents the results of thermoelectric leg engineering to see its effect on thermoelectric performance. The thermoelectric performance assessment was carried out using a numerical simulation method. Input temperature varies from 300 to 1000 K. The thermoelectric design is limited to a pair of negative legs (N-Leg) and positive legs (P-Leg) for modeling simplification. The results show that the choice of thermoelectric material affects the temperature gradientGradient and the resulting power output. This engineering produces a power output of 32,525 mW with an efficiency of 20% at a temperature of 350–400 K. This sandwich material engineering shows poor results because it has a decreasing power value, but it can still be developed for other types of materials and engineering configurations such as terraced or diagonal.
