In the present work, entropy generation in the flow and heat transfer of couple stress fluid through an infinite inclined channel embedded in a saturated porous medium is presented. Due to the channel geometry, the asymmetrical slip conditions are imposed on the channel walls. The upper wall of the channel is subjected to a constant heat flux while the lower wall is insulated. The equations gov...

The effects of radiative heat transfer on the fully developed free convection flow of a viscous incompressible fluid-saturated porous medium between two vertical walls in the presence of a uniform gravitational field have been studied. An exact solution of the governing equations has been obtained. Radiation is found to have significant effects on the velocity field and temperature distribution...

This paper investigates the influence of the effect of viscous dissipation and radiation on natural convection heat transfer from vertical flat plate in a non-Darcy porous media saturated with non-Newtonian fluid of variable viscosity. The wall and the ambient medium are maintained at constant but different levels of temperature. The Ostwald–de Waele power law model is used to characterize the ...

This study investigated the effects of seawater pH (i.e. 8.10, 7.85 and 7.60) and temperature (16 and 19°C) on (i) the abiotic conditions in the fluid surrounding the embryo (viz. the perivitelline fluid), (ii) growth, development and (iii) cuttlebone calcification of embryonic and juvenile stages of the cephalopod Sepia officinalis. Egg swelling increased in response to acidification or warmin...

Macroscopic poroelasticity and effective medium theory are two independent approaches which can be used to analyze the role of pores, cracks, fluid on elastic properties. belongs macroscopic framework thermodynamics whereas expresses properties in terms microstructural characteristics (pore crack shape, etc.) component (fluid properties, solid grain etc.). In this paper, we review fundamental a...

For porous medium containing multiphase fluid, such as oil-wetted with oil–water dual phase its fluid interface will also produce electric double layer (EDL), which play a role in the seismoelectric effects. At this time, principle of effects is more complex. The existing theory for Pride used water-saturated formation, cannot meet actual needs theoretical research exploration formation fluid. ...

A convective stability analysis of the flow in a vertical fluid-saturated porous slab made two layers with different thermophysical properties is presented. The external boundaries are isothermal one them impermeable while other open to an fluid reservoir. This study development previous investigations on onset thermal instability heterogeneous where heterogeneity may be either continuous or pi...
