“…The loss to thermal conductance of 1/Ktem and 1/Kp is shown in the [7,11,12,33,35,38,44,54]. Likewise for 2 nd stage of TEG are optimized by decision making methods such as fuzzy, LINMAP and TOPSIS [9,18,40,43]. The resultant outcomes are 3.3 ≤ TEG (%) ≤ 6.1, 0.045 ≤ entropy-TEG ≤ 0.071 and 1.48W ≤ power ≤ 3.80W for different algorithms is shown in the fig.…”
