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 …

A numerical investigation is performed to analyze the high-temperature heat transfer
behavior in a double-pipe heat exchanger filled with open-cell porous foam. The …

This study obtains the semi-analytical solutions and explores the thermal characteristics of a
thermally developing flow in a parallel plate channel, partially filled with a porous medium at …

In this study, results of a numerical simulation of the 3D laminar mixed convection in an
annulus between two confocal elliptic cylinders are presented. The inner cylinder is heated …

Forced flow and radiation-convection coupled heat transfer in an annulus filled with open-
cell foam was numerically investigated at high temperatures. The Darcy-Brinkman …

An analytical–numerical method for determining the two-dimensional (2D) thermal field in a
layer-inhomogeneous elliptic cylinder (elliptical roller) was developed in the article. A …

In this article, an analytical-numerical approach to calculating a stationary thermal field in the
elliptical region is presented. The eigenfunctions of the Laplace operator were determined …

In this study, heat transfer in a tall, rectangular permeable cavity with active thermal walls is
investigated. Inside the enclosure, the two side walls' central portions are partially cooled at …

The fundamental question in heat transfer engineering is to determine the relationship
between the heat transfer rate and the driving temperature difference. In nature, many …
