“…The reference of heatfunction (P ¼ 0) is generally considered at the adiabatic wall of the cavity or any convenient point (origin or cold-cold junction) as mentioned in previous studies [17,[20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39]. However, in this study, various possible locations of datum of heatfunction (P ¼ 0) and heatfunction boundary conditions are explored and discussed for systems with more than one (case 1) and no adiabatic wall (case 3).…”

“…They considered adiabatic top wall and reference of heatfunction (P ¼ 0) was considered at the top adiabatic wall irrespective of thermal boundary conditions of bottom/side walls. Further, studies on natural convection via heatlines for discretely heated square cavities were carried out for various possible positions of heater on the side as well as bottom wall(s) by Kaluri and Basak [23] and Kaluri et al [24] with the Dirichlet heatfunction boundary condition (P ¼ 0) at the top adiabatic wall.…”

“…1 had been studied numerically by various researchers due to its importance in energy related applications. Some of these studies were [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Ghasemi et al [2] investigated numerically the influence of the magnetic field on buoyancy driven fluid flow in a square nanofluid enclosure filled with Al2O3-water.…”

The natural convection heat transfer has many applications in engineering like solar collectors, cooling of electronic equipment and geothermal engineering. The present work demonstrates the recent publications in the last ten years in this specific subject for a body located in complex shapes like rhombic, wavy, trapezoidal, elliptical and Parallelogrammic enclosure. Many parameters like Ra, Nu, number of undulations, the position of the inner body had been addressed and discuss to draw the main conclusions and recommendations. It is worthy to mention that wavy enclosure had been investigated less than the other simple enclosure shapes due to its complexity. Beside that entropy generation should be included in the future studies in complex shapes of enclosure as this will helps the researchers to extended their studies. The inner bodies inside trapezoidal, parallelogrammic enclosure are very limited and more investigation should be done.

“…Specifically, when the enclosure was tall, the Rayleigh number was high. Basak et al [6,7] used a square cavity to study the influence of distributed heating on natural convection. They showed that thermal mixing and heat distribution inside a square cavity were highly enhanced compared to those in the isothermal hot bottom wall.…”

Heat transfer by natural convection for a centered inner adiabatic circular cylinder inside a trapezoidal enclosure filled with Ag-water nanofluid superposed saturated porous-nanofluid layer is numerically investigated. The inclined left and right walls of the trapezoidal enclosure are insulated. The bottom wall is partially heated at isotherm hot temperature, while the top wall is maintained at isotherm cold temperature. Finite element technique is used to numerically solve dimensionless Navier-Stoke equations for the nanofluid and porous-nanofluid media between inner adiabatic circular cylinder and trapezoidal enclosure. The numerical results are validated with those of Kim et al. [2008] in terms of streamlines and isotherms to check the accuracy of the present program. The validation illustrates a favorable agreement between the present work and Kim et al. The following parameters are studied: Rayleigh number (10 3 ≤ Ra ≤ 10 6 ), Darcy number (10 -1 ≥ Da ≥ 10 -5 ), nanoparticle volume fraction (0 ≤ φ ≤ 0.1), and porous layer thickness (0 ≤ Yp ≤ 100%).
