Abstract
ABSTRACT
The Non-Newtonian fluids in porous medium are widely deployed in energy systems. Motivated by these
developments, in the current study, a numerical simulation is performed on two-dimensional, buoyancy-driven flow
in a porous square cavity filled with non-Newtonian fluid (Casson liquid). The enclosure geometry features vertical
isothermal walls (with one at higher temperature than the other) and thermally insulated horizontal walls. The
conservation of mass, momentum and energy equations are normalized via appropriate transformations and the
resulting dimensionless boundary value problem is solved by the effective technique named as projection method
(Marker and Cell (MAC) algorithm) along with a staggered grid system. Extensive visualizations of the impact of
emerging physical fluid flow parameters (Rayleigh number Ra Darcy number Da, thermal radiation Rd and
Cassonviscoplastic parameterī§ ) on streamline and isotherm distributions in the porous enclosure are presented for
fixed Prandtl number (Pr=6.8). Nusselt number i.e. heat transfer rate is increased with rising values of the thermal
radiation parameter and Darcy number for any value of Rayleigh number. Overall the thermal radiation parameter
and Darcy number plays a vital role in controlling the convective heat transfer within the porous enclosure. The
computations are relevant to hybrid solar collectors, materials fabrication (polymer melts) etc

Key words: KEYWORDS: Free convection, porous enclosure, laminar flow, Non-Newtonian (Casson) fluid, finite difference scheme, Projection Method; flow visualization.
