Heat Transfer From the Cold Wall of a Square Cavity to the Hot One by Oscillatory Natural Convection

Natural convection and wall condensation or evaporation in humid air-filled cavities subjected to wall temperature variations

“…The responses of the confined fluid, when the temperature or the heat flux specified at one of the vertical walls varies periodically, were of concern in most of these studies. An extension to natural convection of fluid in an inclined cavity with a sinusoidal wall temperature on one side wall and a constant temperature on the opposite side wall was reported by Kalabin et al [14,15]. The case of an inclined, porousfilled cavity subjected to the same boundary conditions was conducted recently by Wang et al [13].…”

Second law analysis of periodic heat conduction through a wall

“…It must also be mentioned that heat sources with varying temperatures is an emerging problem in Refs. [5,6], a problem that might require to revisit the usual framework of process analysis. On that purpose, the present problem is oversimplified.…”

Effects of adiabatic extensions on heat transfer through a differentially heated square cavity

“…Numerous investigations of the differentially heated cavity [5][6][7][8] have been carried out since the pioneer work of Bachelor [9], and a number of techniques have been developed for enhancing heat transfer through the differentially heated cavity. In general, the applied techniques for manipulating heat transfer through a differentially heated cavity can be classified into two categories, that is, active and passive approaches.…”
