Valuable reconsideration in the constructal design of cavities

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

“…Therefore it is always highly demanding to seek new heat transfer enhancement techniques, maximize HX efficiency, and propose novel design. Unsurprisingly, this statement accords precisely with the recent academic progress [30][31][32][33].…”

Numerical investigation on baffle configuration improvement of the heat exchanger with helical baffles

“…But this type of heat exchanger has some inherent drawbacks, such as a large pressure drop in the shell side and a dead zone in the back of the segmental baffles, and leading to a serious fouling and high risk of vibration failure on tube bundles [2][3][4][5][6]. A number of new methods were proposed to overcome the above-mentioned drawbacks in shell-and-tube heat exchangers with segmental baffle [7][8][9][10][11][12][13]. STHX with helical baffles (STHXsHB) was firstly proposed by Lutcha and Nemcansky [14].…”

Improvement of constructal tree-like network for “volume-point” heat conduction with variable cross-section conducting path and without the premise of optimal last-order construct

“…To cope with this issue, there are several methods proposed recently [1][2][3][4][5][6][7][8][9][10][11][12]. da Silva et al [1] and Hajmohammadi et al [2] studied cooling problem of a panel with discrete heat sources by laminar forced convection [1] and boundary layer flow [2], respectively, and the optimal spacing of heat sources was found.…”

“…References [3,4] optimized the thickness of conducting thick plate placed between heat source and cold flowing fluid, and References [5,6] studied the heat convection cooling problem with inner duct. Cavities [7][8][9] and fins [10,11] were also usually used to cool the electronic package. Except for methods mentioned above, heat conduction with high conductive route [12] is another important cooling way.…”
