“…Pulsating heat transfer is usually applied in the cold fluid section. 47,55,56 The pulsating pump used in this experiment consists of three main components: a power inverter, piston pump with a fixed head, crankshaft, and moveable shaft. The piston pump and crankshaft are fitted with the straps, and the rotation rate is proportional to both.…”

In industrial-thermal applications, pulsating flow along with carbon-based nanofluids is a well adopted active method, although not in plate heat exchangers (PHEs). The performance of a PHE with carbon-based nanofluids was experimentally evaluated by superimposing pulsating flow along with steady-state flow. The results demonstrated that the use of GNP-water, hybrid GNP/MWCNT-water, and MWCNT-water nanofluids with volume fractions ranging from 0.01% to 0.1% in a steady-state flow led to improved average heat-transfer rates of 1.34, 1.27, and 1.25, respectively. Furthermore, implementation of pulsating flow enhanced the average heat-transfer rate, in comparison to that of the steady-state flow in the same nanofluids, in the range of 10.9%–28.2%, 9%–25.4%, and 7.1%–14.8%, respectively. Pulsating flow in nanofluids improved heat-transfer rate more than it did in pure water owing to the enhancement of the Brownian motion of the suspended carbon-based nanoparticles. In the considered volume fractions from 0.01% to 0.1%, the pulsating flow condition increased the pressure drop by a factor of 1.48, 1.49, and 1.62 for the MWCNT-water, hybrid GNP/MWCNT-water, and GNP-water nanofluids, respectively, in comparison to pure water. The experimental results indicated that the pulsating flow had a more profound influence on the improvement of heat-transfer rate and pressure drop in the case of GNP-based nanofluid than in the others. This could be attributed to the unique platelet shape of the GNP nanoparticles and consequently the higher Brownian motion. The improvement in the heat-transfer rate, obtained through implementation of the pulsating flow condition, outweighed the cost of increase in pressure drop in all the cases. Among the nanofluids considered, the hybrid GNP/MWCNT-water nanofluid exhibited the best overall performance of 1.2.

“…This finding should be considered when implementing different configurations of TEC modules. Another solution to increase the cooling capacity of TEC modules is to utilize nanofluids combined with pulsating 17 and current flows. This strategy allows power to be increased up to 14% between minimum and maximum amplitudes, which is 31% higher than that afforded by continuous water cooling.…”

“…Jaziri et al [17] reported optimizing the design of thermoelectric generators based on low-temperature cosintered ceramic technology. Nassar et al [18] reported an experimental investigation of a forced convective pulsating flow of the air and magnetic field effect on the thermoelectric cooler performance with a Reynolds number of 5871. Their results showed that the temperature differences were between 5.56 • C and 19.8 • C. In addition, the thermoelectric cooler's coefficient of performance ranged from 0.122 to 0.277.…”

Although thermoelectric technology is little-known in the public domain, it presents an exciting alternative solution in many cases where lost heat energy can be quickly recovered to produce electricity. In the present paper, an attempt is undertaken to exploit this energy. For this purpose, an experimental study is conducted to produce electricity with the thermoelectric effect by utilizing a device placed on a parabolic concentrator. The device is placed on a solar tracker. The results obtained for two days of two distinct months, January and June, revealed that the production in June was higher than that in January by around 92.86%. This distinction is due to the concentrated solar beam being different on a day in each month. A vital product was recorded by utilizing the concentrator. This gadget permitted us to take advantage of the limit of sun-based radiation to produce power. The power may be stored with a legitimate stockpiling procedure.
