Abstract

The effect of nanoparticles on unsteady natural convection in a square enclosure filled with a fluid-saturated porous medium have been investigated numerically. The top and bottom horizontal walls of enclosure are considered adiabatic, while the vertical walls are kept at constant temperatures. The mathematical model consists in a set of partial differential equations along with the corresponding boundary conditions and these equations were solved numerically using a Finite Difference (FD) scheme consisting of the Alternating Direction Implicit (ADI) method and the Tri- Diagonal Matrix Algorithm (TDMA). It is found that significant effect of adding the nanoparticles in enhancing the steady heat transfer were obtained at low Rayleigh number. Steady heat transfer enhancement are greater compared to unsteady heat transfer enhancement.
