By a porous medium we mean a material consisting of a solid matrix with an interconnected
void. We suppose that the solid matrix is either rigid (the usual situation) or it undergoes …

Heat transfer continues to be a field of major interest to engineering and scientific
researchers, as well as designers, developers, and manufacturers. Considerable effort has …

This paper presents a combined experimental and numerical study on natural convection in
open-celled metal foams. The effective thermal conductivities of steel alloy (FeCrAlY) …

Abstract The Generalized Integral Transform Technique (GITT) is reviewed as a hybrid
numerical–analytical approach for fluid flow problems, with or without heat and mass …

We present a three-dimensional solution of the steady-state advection-diffusion equation
considering a vertically inhomogeneous planetary boundary layer (PBL). We reach this goal …

In this work we present the GILTT method for the solution of the advection–diffusion equation
utilizing an eddy diffusivity depending on source distance. With this new approach, where no …

Stochastic bifurcations and stability of natural convection within two-dimensional square
enclosures are investigated by different stochastic modelling approaches. Deterministic …

A unified approach for solving convection-diffusion problems using the Generalized Integral
Transform Technique (GITT) was advanced and coined as the UNIT (UNified Integral …

The linear stability of the horizontal through flow in a porous layer saturated by a non-
Newtonian power-law fluid is analysed. The bounding horizontal walls are assumed to be …

The theory and algorithm behind the open-source mixed symbolic-numerical computational
code named UNIT (unified integral transforms) are described. The UNIT code provides a …
