This work is devoted to studying steady-state flow and heat transfer coupled byconduction, convection, and surface radiation in an unvented Trombe wall subjected to solar flux. The lateral surfaces exchange heat with the indoor and outdoor environments, while the horizontal surfaces are assumed to...
The results of an analytic investigation of heat transfer through a finned surface are presented; the limits of applicability of the assumption that the heat-transfer coefficient remains constant over the entire height of the fin are defined; and recommendations are given for calculations in the ...
1 Heat transfer through the window is steady since the surface temperatures remain constant at the specified values. 2 Heat transfer through the wall is one-dimensional since any significant temperature gradients will exist in the direction from the indoors to the outdoors. 3 Thermal conductivity...

The boiling heat transfer coefficient, hboil, is defined as[1]hboil=qCHFAsurfΔTsatwhere Asurf is the projected geometrical area where boiling occurs and ΔTsat=Twall−Tsat the wall superheat. From: Comprehensive Microsystems, 2008 About this pageAdd to MendeleySet alert Discover other topics...
transfer to the outer wall. The second term of Eq. (9) is related to the conductive heat transfer through the composite pipe:λjrjare the thermal conductivity and the radius of the material (air and steel). The third element of Eq. (9) is due to the convection to the inner wall. ...
Experiments were conducted to determine the average heat transfer coefficients on three wall segments between blockages with holes in a wide rectangular channel. Eight different configurations of the holes in the blockages - two diameters and four aspect ratios of the holes - were examined. The pre...

The effects of the incident solar flux, the internal aspect ratio of hollow bricks and the thermal emissivity on the fluid flow and heat transfer through the building walls are analyzed. The results show that the hollow brick wall of type 1 improves the thermal resistance and leads to the ...
The radiation heat transfer through the insulation system has been modelled via the two flux approximation. The numerical results were compared with the experimental data from the guarded hot box for model validation, as well as to assess the effectiveness of the reflective foils in changing the ...
