An experimental investigation on the performance of TEGs with a compact heat exchanger design towards low-grade thermal energy recovery

Investigation of turbulent entropy production rate with SWCNT/H2O nanofluid flowing in various inwardly corrugated pipes

“…at the Re = 5 × 10 . 3 The contours are also similar in the three corrugated pipes considered. The high intensity was noticed in regions where TED is maximum.…”

“…These hybrid heat transfer fluids have been found to possess high thermal conductivity compared with the base fluid and also have some advantages over conventional heat transfer fluids, which include higher heat conduction rate, lower pumping power, stability, and among others. 3,4 Various works on the enhancement of CHTP using geometry modification such as the usage of ribs, 5,6 vortex generator, [7][8][9] wavy channel, 10,11 twisted tape inserts, [12][13][14] corrugated tube, [15][16][17] noncircular cross-section, [18][19][20] helical tube, 21 and converging pipe 22 have been reported in the literature. In addition, among the various geometry modifications examined so far, the inwardly corrugated pipe is preferable due to its high thermal efficiency and ease of maintenance.…”

Performance evaluation of an automotive thermoelectric generator with a non-isometric distributed fin heat exchanger

“…In addition, it has the advantages of low maintenance cost, high reliability, and no moving parts. [1][2][3][4] Thermoelectric generation technology was rst applied in the aerospace eld [5][6][7] and then in military applications 8 as well as wearable devices. 9,10 Researchers have transplanted this technology into the automotive sector and created many kinds of automobile exhaust thermoelectric generators (ATEGs).…”

Comparative study of heat pipes and liquid‐cooling systems with thermoelectric generators for heat recovery from chimneys

“…It showed that the HPTEG prototype system's performance is satisfactory with 83% system thermal efficiency. An experimental work was presented by Yang et al 23 on the performance of a TEG coupled with low compact heat exchanger for waste heat recovery. Their outcomes revealed that despite that the obtained conversion efficiency of the proposed TEG is 1.64% at a temperature difference of 96.4 C, it achieved a high volumetric power density of 86.4 kW/m 3 and a negligible power consumption of 0.64% of the total output power output.…”
