Double-diffusive natural convection in trapezoidal enclosures

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

“…Natural convection heat transfer and fluid flow was studied for porous or non-porous medium trapezoidal enclosures mostly at differentially heated temperature boundary conditions, see Kumar and Kumar [16], Moukalled and Acharya [17], Baytas and Pop [18], Papanicolaou and Belessiotis [19], Van Der Eyden et al [20], Moukalled and Darwish [21,22], Boussaid et al [23], Moukalled and Darwish [24], Kuyper and Hoogendoorn [25], Sadat and Salagnac [26]. However, to our best knowledge, partially cooled right-angle trapezoidal enclosure has not been considered yet.…”

Numerical analysis of natural convection in an inclined trapezoidal enclosure filled with a porous medium

“…The study of convective flow in these kind of geometries are more difficult than that of square or rectangular enclosures due to presence of sloping walls. Flow and heat transfer in triangular [26][27][28][29][30], parallelogram [31] and trapezoidal enclosures [32][33][34][35][36][37][38][39] is mostly analyzed in the literature. The natural convection in an inclined trapezoidal enclosure at different inclination angles filled with a viscous fluid has been studied by Lee [34].…”

Natural Convection and Entropy Generation in Nanofluid Filled Entrapped Trapezoidal Cavities under the Influence of Magnetic Field

“…They showed that non-uniform heating of the bottom wall produces greater heat transfer rate at the center of the bottom wall than uniform heating. Eyden et al [11] numerically and experimentally studied the turbulent double diffusive natural convection in a trapezoidal enclosure which mimics an idealized situation in underground coal gasification. They reported that the numerical model can reproduce the essential features of the process.…”
