Comparison of selected shell and tube heat exchangers with segmental and helical baffles

Theoretical and numerical study of a shell and tube heat exchanger using 22% cut segmental baffle

“…Abbasian Arani et al 12 Segmental baffle 07 0.600 Kunwer et al 16 Segmental and helical Baffle 10 0.400 Gugulothu et al 17 Segmental baffle 10 1.150…”

“…Gugulothu et al 9 further numerically studies the STHX with 22% cut SB along the nanofluids and found improvement in the case of Al 2 O 3 nanofluids at 5% volume concentrations. Kunwer et al 10 investigated the STHX with various configurations of baffles like segmental baffle with 30° cuts, and 50° cuts. They found that the effectiveness decreases with an increase in baffle cuts.…”

Effect of helical baffles and water‐based Al2O3, CuO, and SiO2nanoparticles in the enhancement of thermal performance for shell and tube heat exchanger

“…The author noticed that the CHB is a superior, single shell pass than the segmental baffle STHX. Kunwer et al 13 experimentally and numerically studied STHX by varying various baffle geometries (segmental, 30° and 50° SB cut, Align baffle with 30° and 50°) and comparison made with SB and HB of 25° helical angles. The author found a 22% effectiveness improvement in STHX without baffles, 2.5% with 50° align baffles.…”

Impact of hybrid nanofluids (Ag‐TiO2/H2O) on improving the performance of a heat exchanger with turbulent induction elements

“…They are employed in food processing equipment, thermal power plants, cooling and air conditioning equipment, petrochemical, and pharmaceutical industries, and the like, encountering dilemmas such as efficient use, thermal energy recovery, and conversion. [1][2][3] Nowadays, heat exchangers have extensive applications in diverse devices such as boilers, condensers, evaporators, cooling towers, fan coil preheaters, radiators, and the like. Among the most efficient approaches to promote heat transfer in heat exchangers is the use of twisted tape, which improves heat transfer by generating a rotating fluid flow while with the least amount of errors in pressure loss.…”

“…Heat exchangers are almost the most frequently used elements in the industry. They are employed in food processing equipment, thermal power plants, cooling and air conditioning equipment, petrochemical, and pharmaceutical industries, and the like, encountering dilemmas such as efficient use, thermal energy recovery, and conversion 1–3 . Nowadays, heat exchangers have extensive applications in diverse devices such as boilers, condensers, evaporators, cooling towers, fan coil preheaters, radiators, and the like.…”
