Natural convection in right-angle porous trapezoidal enclosure partially cooled from inclined wall

Maximum density effects on buoyancy-driven convection in a porous trapezoidal cavity

“…These types of cavities are used to store heat using porous material underground. Greek letters α m effective thermal diffusivity, have been published [20][21][22][23][24][25][26][27][28][29]. However, to the best of our knowledge there are no studies on the effects of the maximum density on natural convection for these types of cavities.…”

Effect of buoyancy ratio on unsteady thermosolutal combined convection in a lid driven trapezoidal enclosure in the presence of magnetic field

“…al. [34] for three different cases in which cooler is placed adjacent to the top wall (case-I), in the middle of the inclined wall (case II) and adjacent to the bottom wall (case II) with the aspect ratio 0.5 and found a good agreement which are shown in Fig. 3.…”

A comprehensive heatline based approach for natural convection flows in trapezoidal enclosures: Effect of various walls heating

“…The computational domain consists of 28 Â 28 bi-quadratic elements representing 57 Â 57 grid points in cartesian coordinate system and grid generation with iso-parametric mapping has been discussed in earlier work [46,47]. The Galerkin finite element method has been used with bi-quadratic elements corresponding to lesser number of nodes, as that smoothly capture the non-linear variations of the field variables, which are in contrast with finite difference/finite volume solutions available in the literature [33]. Bi-quadratic elements are used for the finite element method and the detailed description of element basis functions can be found elsewhere [48,51].…”

“…Kuyper and Hoogendoorn [32] investigated laminar natural convection flow in trapezoidal enclosures to study the influence of the inclination angle on the flow. Varol et al [33] studied natural convection within trapezoidal enclosure partially cooled from inclined wall. They considered three different cases.…”
