The demand for clean and sustainable energy has driven the need for efficient storage.
Hydrogen being a carbon–neutral energy carrier, offers a versatile solution. However …

This paper presents a comprehensive review of significant studies that are relevant to
thermal energy storage technologies using phase change materials (PCMs). The review …

Renewable energy systems may be turning to be more effectual and inexpensive and
contributing lion's share of whole energy utilization in today's power hungry planet. The …

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 …

This study provides a critical review of Underground Hydrogen Storage (UHS), emphasizing
its potential as a viable energy storage option despite several associated challenges. These …

Dissolution of a porous medium creates, under certain conditions, some highly conductive
channels called wormholes. The mechanism of propagation is an unstable phenomenon …

We present numerical and experimental results for buoyancy-induced flows in high porosity
metal foams heated from below. A Brinkman–Forchheimer-extended Darcy flow model and …

A combined numerical and experimental study is reported of solid/liquid phase change in
porous media with natural convection in the melt region. The model is based on volume …

The momentum balance at the interface between a liquid and a porous substrate is
investigated for a configuration with forced flow parallel to the interface. An heterogeneous …

Natural convection heat transfer in a differentially heated and vertically partially layered
porous cavity filled with a nanofluid is studied numerically based on double–domain …
