Experimental investigation of conjugate natural convection heat transfer from a horizontal isothermal cylinder with a nonisothermal longitudinal plate fin at various angles

Melting process of PCM with Carreau – Yasuda non-Newtonian behavior in a shell and tube heat exchanger occupied by anisotropic porous medium

“…Many researchers have worked on conjugate heat transfer (Tolpadi and Kuehn, 1985;Heindel et al, 1995;Mehryan et al, 2018Mehryan et al, , 2019. The conjugate natural heat transfer in a cubic chamber with thick walls and vertical thermal fins was studied by Costa (2012).…”

Concurrent calorimetric and interferometric studies of steady-state natural convection from miniaturized horizontal single plate-fin systems and plate-fin arrays

“…On the basis of data correlation, Jones and Smith [16] concluded that fin spacing is the prime geometric variable. The effects of varying the fin length could not be reflected by this correlation because only one fin length was applied in their experiments as was generally the case with earlier interferometric studies [16,17,18,19,20].…”

“…Fin spacing, mm, i.e. the inter-fin separation distance, see Table 1 Ra Rayleigh number t Fin thickness, mm, see Table 1 T Absolute temperature, K Most experimental work on natural convection heat transfer from horizontal fin arrays and fin systems applied the calorimetric technique [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15], two [16,17] used the Mach-Zender interferometric technique, and three [18][19][20] applied the differential interferometric technique. Application of earlier calorimetric or interferometric techniques mostly dealt with large fin arrays, except [14,15], which studied miniaturized horizontal plate-fin arrays.…”

“…The first was on a rectangular fin on a partially heated horizontal base and the other on a short horizontal rectangular fin array. Only four studies were found that dealt with single fin systems [17,19,21,23]. Reference [17] applied a Mach-Zender interferometric technique, [19] applied a differential interferometric technique, [21] a numerical method, and [23] a concurrent calorimetric and interferometric technique.…”

“…Mobedi et al [21] presented results of a numerical investigation to reveal the mechanism of two dimensional steady state laminar air flow and heat transfer from a vertical rectangular fin attached to a partially heated horizontal base. The flow pattern of the problem considered was a two dimensional transverse chimney flow similar to the flow pattern on one side of the vertical symmetrical axis sketched by [19] for the horizontal single plate fin system and in [17] for the single longitudinal fin positioned pointing upwards from a horizontal cylinder visualized using a Mach-Zender interferometer.…”
