Laminar free convection in undulated cavity with non-uniform boundary conditions

Abstract: In the present work, the influence of non-uniform boundary conditions on natural convection in inclined rectangular cavities differentially heated is studied. The hot wall is wavy with three undulations. The aspect ratio of the cavities has also been changed. Various inclination angles were performed. The flow and the heat transfer are calculated by solving both Navier-Stokes and the energy equations with finite volume method in the primitive formulation. The sinusoidal distribution of temperature is imposed a… Show more

“…Oztop et al (2011) considered the impact of volumetric heat sources on flow structures inside a wavy-walled cavity. Sabeur-Bendehina et al (2011) studied the convection flow with non-uniform boundary conditions in an inclined wavy cavity. Dogonchi et al (2019b) investigated the nanofluid flow in parallel disks under the effects of several physical parameters.…”

“…Therefore, knowledge about flow and heat transfer through wavy surfaces becomes important in this context. Solar collectors, condensers in refrigerators, cavity wall insulating systems, grain storage containers, industrial heat radiators, for example, are a few of many applications where wavy surfaces are encountered to transfer small or large scale heat [1,2]. The focus on the area of flow and heat transfer past wavy surfaces in complex enclosures like square, trapezoidal, and rectangular has been intensifying over the years due to the increasing interest of researchers from applied mathematics, mechanical, and chemical engineering as well as from biomechanics and engineering mechanics.…”

“…Saha et al [9] solved the natural convection problem for sinusoidal and inclined corrugation geometry and different heat source sizes. Recently, Bendehina et al [10] reported a series of numerical simulations on laminar natural convection in inclined rectangular cavities with undulations and a sinusoidal temperature distribution on the cold wall. A thorough analysis conducted by Chin-Lung Chen et al [11] highlighted the effects of various shaped concave enclosures on convection heat transfer.…”
