Natural convection heat transfer from a hot rectangular and a square corrugated plate to a cold flat plate

Abstract: Experimental study of natural convection heat transfer across air layers bounded by a lower hot rectangular and a square corrugated plates to an upper cold flat plate has been carried out. The surroundings of this space are adiabatic. The effect of the angle of inclination, the aspect ratio, the temperature potential and the Rayleigh number on average heat transfer coefficients are investigated within a range of 0°<0'Z-75 °, 2.33<_A<6.33, 10° Show more

“…There are many research works available in the literature related to grooved channels and isolated heated walls of the defined geometry, to study the combined convective flow scenarios 8,21,[33][34][35][36][37][38][39][40] There is no previous existing numerically simulated research work that has been performed on the transient free convective flows problem in a modified geometry by using a fourth-order compact finite-difference scheme. This is also imperative to comprehend the 3-D natural and forced convective flow scenarios in the defined considered geometries.…”

“…Studying the flow patterns of forced, forced‐mixed, and natural convection, numerous experimental, and numerical research efforts have been made on (T, U, V, H, and I)‐shaped geometries, customized chamfered channels, various thermal strips, and isolated sources of heat located on the boundary lines of the defined geometry 28–49 . There are no studies done to employ a higher order compact scheme without transformations and uniform mesh spacing to study free convective heat flows in a porous‐corrugated chamber.…”
