Experimental and numerical investigations of shell-side thermo-hydraulic performances for shell-and-tube heat exchanger with trefoil-hole baffles

Numerical investigation on a novel shell-and-tube heat exchanger with plate baffles and experimental validation

“…To date, researchers have successfully invented different novel shell-and-tube heat exchangers, like annular orifices [3], rod baffles [4], double segmental baffles [5], ring supports [6], flower-like baffles [7,8], conical strip inserts [9], trefoil-hole baffles [10], rod baffles with arc cuts [11], twisted oval tubes [12,13], helical tubes [14], helical coiled tubes [15], porous structures [16,17], and helical baffles [18][19][20][21][22][23][24][25][26][27][28][29]. Those replete of new inventions were proposed to enhance heat transfer (inserts), or to reduce power consumption (rod baffles), or to increase cost-efficiency (twisted or helical tubes), or to simplify manufacturing/assembling process (ring supports).…”

A Novel Modeling of Molten-Salt Heat Storage Systems in Thermal Solar Power Plants

“…This is typically done via the Bell-Delaware method [36][37][38], which is an empirical method based on numerous experiments with shell-and-tube heat exchangers. Recently, there have also been published some numerical studies that reconfirmed its validity [39][40][41].…”

CFD Analysis and Enhancement of Heat Transfer in Compact Shell and Tube Heat Exchanger by Using Camphor-Water

“…The thermo physical properties of nano fluid mixture were forecast by analytical method. Yonghua You [9] with trefoil-hole baffles the heat transfer rate is effectively enhanced on the shell side, meanwhile, the flow resistance increases substantially. A closer look at above research works reveals that the heat transfer rate in shell and tube heat exchanger is improved by using different fluids.…”
