A New Look at Porous Media Fluid Mechanics — Darcy to Turbulent
A. Dybbs,R. V. Edwards +1 more
TL;DR: In this paper, the results of laser anemometry and flow visualization studies of the flow of liquids in porous structures are presented and three dimensional velocity profiles and movies of dye streaklines are shown.

Structural properties of packed beds — A review
D. P. Haughey,G. S. G. Beveridge +1 more
TL;DR: Some structural properties of packed bed systems on both the local and overall scales which are available in the literature and of interest in chemical engineering applications are discussed in this paper, where regular and random packings of uniformly sized spheres are initially analyzed as a basis for the later examination of the more general case of random packed beds containing particles of various sizes and shapes, with or without restraining surfaces.
Journal ArticleDOI
Effects of boundary conditions on non-Darcian heat transfer through porous media and experimental comparisons
TL;DR: In this article, a numerical simulation of forced convective incompressible flow through porous beds was performed in terms of non-dimensional parameters that successfully cast together all the pertinent influencing effects.
Journal ArticleDOI
The Prediction of the Emissivity and Thermal Conductivity of Powder Beds
Samuel Sumin Sih,Joel W. Barlow +1 more
TL;DR: In this article, a simple model for estimating the emissivity of the surface of a powder bed by knowing only the bed porosity and its solid emissivities is presented, and the model is compared with experimental measurements for powder beds of alumina, silicon carbide, and iron.

Nusselt number and friction factor correlations for packed bed solar energy storage system having large sized elements of different shapes
TL;DR: In this article, the effect of system and operating parameters on heat transfer and pressure drop characteristics of packed bed solar energy storage system with large sized elements of storage material was investigated and correlations have been developed for Nusselt number and friction factor as function of Reynolds number, sphericity and void fraction.
