Natural convection of power law fluids in inclined cavities

Simulation of double diffusive MHD (magnetohydrodynamic) natural convection and entropy generation in an open cavity filled with power-law fluids in the presence of Soret and Dufour effects (Part I: Study of fluid flow, heat and mass transfer)

“…Natural convection of Newtonian and non-Newtonian power law type fluids in two-dimensional rectangular tilted enclosures was investigated numerically by Khezzar et al [19]. They indicated shear thinning and thickening result in significant increases and decreases, respectively, in the heat transfer rate in comparison to the heat transfer rate of a Newtonian fluid.…”

FDLBM simulation of entropy generation in double diffusive natural convection of power-law fluids in an enclosure with Soret and Dufour effects

“…For a purely-viscous non-Newtonian fluid which follows the Ostwald-De Waele (i.e. power-law) model the shear stress tensor is [3][4][5] …”

“…where D ij indicates the rate-of-deformation tensor for the two dimensional Cartesian coordinate and l a is apparent viscosity that is derived for the two-dimensional Cartesian coordinates as [3][4][5] …”

“…Natural convection of power-law fluid in enclosures has been considered immensely by researchers [1][2][3][4][5] due to its wide applications in various industries such as polymer industry, metal processing, food reservation and cooling systems. However, the studies have been restricted to heat transfer while mass transfer plays a crucial role in the mentioned industries.…”

Natural convection in tilted rectangular cavities due to bidirectional temperature gradient

“…Munir et al [9], reported the fluid flow behavior and the characteristic of heat transfer from a differentially heated enclosure walls and tilted at various inclination angles using the double distribution function lattice Boltzmann numerical scheme with the same lattice structure. Further, Khezzar et al [10], studied two-dimensional natural convection in fluid filled cavities heated from below with varied inclination angle numerically. A year later, Thamer Khalif Salem [11], conducted an experimental work to investigate the influence of inclination angle on natural heat transfer in a rectangular enclosure for three inclination angles; three mass flow rates and five heat fluxes.…”
