Raiative effect on natural convection flows in porous media

Research Abstract
Aregular two- parameter perturbation analysis based upon the boundary layer approximation is presented here to study the radiative effects of both firs- and second- order resistances due to a solid matrix on the natural convection flows in porous media

Natural convection from a vertical plate in a porous medium using Brinkmans model

Research Abstract
A regular perturbation analysis is presented for the following laminar natural convection flow of Newtonian fluids with temperature -dependent effective viscosity: a freely -rising plane plume, the flow above a horizontalline source on an adiabatic surface and the flow adjacent to a vertical uniform flux surface for porous medium

Classes of Algebras with the Amalgamation Property‏

Research Abstract
We introduce an abstract class of algebras that is a proper reduct of both Pinter’s substitution algebras and cylindric algebras. We show that the class of representable algebras has the amalgamation property. We thus obtain a variety V of cylindric-like algebras such that has the interpolation property but not the strong interpolation property.
