A macroscopic particle modelling approach for non-isothermal solid-gas and solid-liquid flows through porous media

Accommodative Behavior of Non-porous Molecular crystal at Solid-Gas and Solid-Liquid Interface

Molecular crystals demonstrate drastically different behavior in solid and liquid state, mainly due to their difference in structural frameworks. Therefore, designing of unique structured molecular compound which can work at both these interfaces has been a challenge. Here, we present remarkable 'molecular' property by non-porous molecular solid crystal, dinuclear copper complex (C6H5CH(X)NH2)2...

Models for Non-Isothermal Compositional Gas-Liquid Flow and Transport in Porous Media

A “v2-f Based” Macroscopic K-Ε Model for Turbulent Flow through Porous Media

In this paper a new macroscopic k-ε model is developed and validated for turbulent flow through porous media for a wide range of porosities. The morphology of porous media is simulated by a periodic array of square cylinders. In the first step, calculations based on microscopic v2 − f model are conducted using a Galerkin/Least-Squares finite element formulation, employing equalorder bilinear ve...

Natural convection solid/liquid phase change in porous media

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 averaged transport equations, while phase change is assumed to occur over a small temperature range. Experiments are performed in a vertical, square enclosure using gallium and glass beads as the fluid and the porous matrix...

Analytical Solutions for Non-linear Conversion of a Porous Solid Particle in a Gas-ii. Non-isothermal Conversion and Numerical Verification

In Part I, analytical solutions were given for the non-linear isothermal heterogeneous conversion of a porous solid particle. Account was taken of a reaction rate of general order with respect to the gas reactant, intrinsic reaction surface area and effective pore diffusion, which change with solid conversion and external film transport. In this part, the analytical solutions are extended to no...
