The present work involves the numerical simulation of forced convective incompressible flow through porous media, and the associated transport processes. A full general model for the momentum equation was employed. The mathematical model for energy transport was based on the two-phase equation model which assumes no local thermal equilibrium between the fluid and the solid phases, The investiga...

We discuss spatio-temporal pattern formation in two separate thermal convective systems. In the first system, hydrothermal waves (HTW) are modeled numerically an annular channel. A temperature difference is imposed across channel, which induces a surface tension gradient on free of fluid, leading to flow towards cold side. The axially symmetric along with internal circulation for small differen...

this work presents the heat transfer characteristics of a new type of porous radiant air heater that operates on the basis of effective energy conversion method between flowing gas enthalpy and thermal radiation. at each layer, the gas and solid phases are considered in non-local thermal equilibrium, and combustion in the porous radiant burner is modeled by considering a non-uniform heat genera...

Abstract The onset of natural convection in a fluid-saturated anisotropic porous layer, which rotates about the vertical axis, under hypothesis local thermal non-equilibrium, is analysed. Since porosity medium assumed to be high, more suitable Darcy-Brinkman model adopted. Linear instability analysis conduction solution carried out. Nonlinear stability with respect $$L^2$$ <mml:math xmlns:mml="...
