The paper presents results of the modelling heat transfer at film boiling a liquid in porous medium on vertical heated wall. Such processes are observed cooling high-temperature surfaces pipes, microstructural radiators etc. Heating conditions wall were constant temperature or flux.
 An analytical solution was obtained for problem fluid flow and using model Darcy-Brinkman. It shown that le...

In this paper, we study the stationary incompressible power law fluid flow in a thin porous medium. The media under consideration is bounded perforated 3D domain confined between two parallel plates, where distance plates very small. perforation consists an array solid cylinders, which connect perpendicular direction, distributed periodically with diameters of small size compared to period. For...

Abstract Thermal convection in a horizontally isotropic bi-disperse porous medium (BDPM) uniformly heated from below is analysed. The combined effects of uniform vertical rotation and Brinkman law on the stability steady state momentum equations BDPM are investigated. Linear nonlinear analysis conduction solution performed, coincidence between linear instability thresholds $$L^2$$ <mml:math xml...

Please cite this article in press as: M. Sankar et a Mass Transfer (2012), http://dx.doi.org/10.1016 Double-diffusive convection in a vertical annulus filled with a fluid-saturated porous medium is numerically investigated with the aim to understand the effects of a discrete source of heat and solute on the fluid flow and heat and mass transfer rates. The porous annulus is subject to heat and m...

A numerical investigation of forced convection in a channel with hot solid block inside a square porous block mounted on a bottom wall was carried out. The lattice Boltzmann method was applied for numerical simulations. The fluid flow in the porous media was simulated by Brinkman-Forchheimer model. The effects of parameters such as porosity and thermal conductivity ratio over flow pattern and t...

The forced convection heat transfer in high porosity metal-foam filled tube heat exchangers are studied in this paper. The Brinkman Darcy momentum model and two energy equations for both solid and fluid phases in porous media are employed .The study shows that using metal-foams can significantly improve the heat transfer in heat exchangers. Keywords—metal foam, Nusselt number, heat exchanger, h...

This article involves the study and analysis of fully developed flow a magnetorheological fluid through non-isotropic porous medium under effect an external, uniform, transversal magnetic field. Permeability is taken as exponential distribution function transverse direction. The Darcy-Brinkman-Lapwood-Lorentz equation for in media has been used solved non-slip boundary conditions by Modified Ho...

porous media has interesting features in compared with free flame combustion due to the extended of the lean flammability limits and lower emissions. advanced new generation of internal combustion (ic) engines are expected to have far better emissions levels both gaseous and particulate matter, at the same time having far lower fuel consumption on a wide range of operating condition. these crit...
