Numerical investigation of natural convection in a rectangular enclosure due to partial heating and cooling at vertical walls

A brief review of natural convection in enclosures under localized heating with and without nanofluids

“…50 years later (Batchelor) studied 33 the subject analytically with high aspect ratio cavities, typical for ther-34 mal insulation of buildings. Few years later, Poots performed one of 35 the earliest trials on solving the problem of natural convection numeri- 36 cally. Ostrach [1], Bejan [2] and De Vahl Davis [3] solved the problem nu-37 merically with different aspect ratio cavities and, similar to previous 38 studies, with isothermal boundary conditions.…”

Effects of heater location and heater size on the natural convection heat transfer in a square cavity using finite element method

“…In general, the average Nu increases with increasing Rayleigh number [35,36]. However, as indicated in Fig.…”

Buoyancy enhanced natural convection inside the ventilated square enclosure with a partition and an overhanging transverse baffle

“…Cianfrini et al [12] found that the heat transfer rate decreases when aspect ratio of cavity increases. Alam et al [13] highlighted that the heat transfer was maximum when the aspect ratio is one with Pr = 100 and Ra = 10 3 to 10 6 . Arefmanesh et al [14] performed the study on the square cavity containing air with baffle and indicated that the heat transfer contribution by the baffle was higher than the hot wall itself.…”
