Transient natural convection in prismatic enclosures of arbitrary cross-section

Transient natural convective heat transfer in a trapezoidal cavity filled with non-Newtonian nanofluid with sinusoidal boundary conditions on both sidewalls

“…Initially, Lee [5] performed a numerical and experimental flow visualization study of heat transfer in a differentially heated trapezoidal cavity filled with pure fluid. Meanwhile, Karyakin [6] simulated the flow and the temperature fields for various inclination angles of the sloping wall and showed that the heat transfer rate increased as the angle of the sloping wall increased. Chamkha and co-workers [7][8][9][10][11] investigated heat and mass transfer in various types of cavities under different conditions.…”

Heatline visualization of natural convection in a trapezoidal cavity partly filled with nanofluid porous layer and partly with non-Newtonian fluid layer

“…Lee [8] firstly performed a numerical and experimental flow visualization study and heat transfer in a differently heated trapezoidal cavity filled with pure fluid. Karyakin [9] has simulated the flow and temperature fields for various inclination angles of the sloping wall and showed that the heat transfer rate increase with the increasing angle of the sloping wall. However, no work has been reported in literature on natural convection fluid flow and heat transfer in trapezoidal cavity partly filled with a porous medium.…”

Natural Convection in a Trapezoidal Enclosure Heated from the Side with a Baffle Mounted on Its Upper Inclined Surface

“…[4][5][6][7]) is solved numerically using the control volume method. A collocated variables approach is adopted, and the special Momentum Weighted Interpolation Method for the calculation of the mass fluxes across the control volume faces [15] that embodies the SIMPLE algorithm of Patankar [16] is employed to suppress oscillatory checkerboard fields.…”

“…Lam et al [4] reported similar experimental and numerical results for a trapezoidal cavity composed of two vertical adiabatic sidewalls, a horizontal hot bottom wall, and an inclined cold top wall. Karyakin [5] reported on transient natural convection in a trapezoidal cavity with parallel top and bottom walls and inclined sidewalls. Lee [6,7] and Peric [8] presented numerical results (up to a Rayleigh number of 10 5 ) for laminar natural convection in trapezoidal enclosures of horizontal, insulated bottom and top walls and inclined sidewalls that are maintained at different uniform temperatures.…”
