چکیده
This paper is based on the numerical investigation of natural convection two vertical enclosure square and triangular cavity with air filled. The consist adiabatic hot cold wall wide range Rayleigh number from 103 to 106 aspect ratio 1 10 at interval 2.5. Flow patterns isotherm plots were used display results, for every case, local mean Nusselt values also produced. results show that an increase in numbers greatly increases heat transfer, intensity, average a particular ratio. Keyword: ANN (average number), AR (aspect ratio), LNN (local Nu (Nusselt Pr (Prandtl Ra (Rayleigh number).

Numerical Study of Natural Convection in a Square Cavity Filled with a Porous Medium Saturated with Nanofluid
Steady state natural convection of Al2O3-water nanofluid inside a square cavity filled with a porous medium is investigated numerically. The temperatures of the two side walls of the cavity are maintained at TH and TC, where TC has been considered as the reference condition. The top and the bottom horizontal walls have been considered to be insulated i.e., non-conducting and impermeable to mass...
متن کاملInteraction of laminar natural convection and radiation in an inclined square cavity containing participating gases
Two-dimensional numerical study of flow and temperature fields for laminar natural convection and radiation in the inclined cavity is performed in the present work. The walls of the square cavity are assumed kept at constant temperatures. An absorbing, emitting, and scattering gray medium is enclosed by the opaque and diffusely emitting walls. The set of governing equations, including conservat...
متن کاملMixed convection study in a ventilated square cavity using nanofluids
This work indicates a numerical study on the laminar heat transfer mixed convection in a square cavity with two openings (an inlet and an outlet) on vertical walls through which nanofluid flows. Two flow directions are examined: i) ascending flow which enters the bottom opening and exits the upper opening; ii) descending flow which enters the upper opening and exits the bottom opening. The asce...
متن کاملCFD analysis of natural convection heat transfer in a square cavity with partitions utilizing Al2O3 nanofluid
In the present study, natural convective heat transfer in a partitioned square cavity utilizing nanofluids is studied. The vertical left and right walls are considered as the hot and cold walls, respectively and the partitions assumed to be adiabatic. The nanofluid used in this study is Al2O3 with the volume fraction of 20%. It is assumed that nanofluid is a single phase f...
