“…where 𝐴𝐴𝑅𝑅 is the aspect ratio of the cavity (L/a in Fig. 31), 𝐴𝐴 𝑤𝑤 the cavity wall area and 𝐴𝐴 𝑐𝑐𝑐𝑐 the convective zone area (see Abbasi-Shavazi et al, 2020), which accounts for the stagnant zone in pure convection (being the surface of the volumes shown in Fig. 31 for the 22.5° and 45° orientations added to the aperture area).…”

“…Free, natural, convection is a popular phenomenon in many applications in which the fluid flow is controlled by bouncy without applying any external forces. Natural convection in the closed enclosure has attracted many researchers, who apply an extensive study to modify the possibility of heat transfer manipulation because it plays a major role in many engineering applications such as cooling systems of chips and microelectronic devices, reactors, geothermal systems, and solar collectors [1][2][3][4][5][6][7].…”

Numerical simulation of MHD free convection in a two-dimensional trapezoidal cavity of a hybrid nanofluid has been carried out in this research. The cavity is heated sinusoidal from the bottom wall, and the inclined walls are cooled while the top wall is isolated. The hybrid nanofluid (MgO-Ag/water) has been used as a working fluid. The numerical simulation has been validated with past papers and met a good agreement. The considered parameters are a range of Rayleigh number (Ra= 103 to 106), Hartmann number (Ha= 0 to 60) and volume fraction (f= 0 to 0.02). The results are presented as isotherms, stream functions, local and average Nusselt numbers, from which it is observed that the strength of the stream functions and isotherms increases with the increase of the Ra and ϕ while the increase in Hartmann number reduce the circulation of the flow and increases the isotherms strength. Also, the Nusselt number is increases with Ra and ϕ while it decreases with Ha.
