Abstract
The existing work is focused on the numerical modelling of mixed convection of Cu-water nanofluid in a square enclosure filled with non-darcian fluid saturated porous medium. The enclosure object has cooled vertical walls and insulated horizontal walls. Finite volume method has been employed to solve the generalised Darcy-Brinkmann Forchheimer extended momentum and energy equations. The parametric study has been taken out for wide ranges of Richardson number, Darcy number and solid volume fraction. The performance of nanofluid is tested inside an enclosure by using solid volume fraction and compared with respect to base fluid (water). A fair degree of precision can be found between the present and previously published work. The results are presented in the form of streamlines, isotherms, average nusselt number and velocity graphs; it clearly explained the influence of flow governing parameters on heat transfer rate and fluid flow within the enclosure.
