TLDR
In this paper, an introduction to convection in porous media assumes the reader is familiar with basic fluid mechanics and heat transfer, going on to cover insulation of buildings, energy storage and recovery, geothermal reservoirs, nuclear waste disposal, chemical reactor engineering and the storage of heat-generating materials like grain and coal.Abstract:
This introduction to convection in porous media assumes the reader is familiar with basic fluid mechanics and heat transfer, going on to cover insulation of buildings, energy storage and recovery, geothermal reservoirs, nuclear waste disposal, chemical reactor engineering and the storage of heat-generating materials like grain and coal. Geophysical applications range from the flow of groundwater around hot intrusions to the stability of snow against avalanches. The book is intended to be used as a reference, a tutorial work or a textbook for graduates.read more

Conceptions for heat transfer correlation of nanofluids
Yimin Xuan,Wilfried Roetzel +1 more
TL;DR: In this article, the authors proposed two different approaches for deriving heat transfer correlation of the nanofluid, and investigated the mechanism of heat transfer enhancement of the nano-fluid.

Entropy generation minimization: The new thermodynamics of finite-size devices and finite-time processes
TL;DR: Entropy generation minimization (finite time thermodynamics, or thermodynamic optimization) is the method that combines into simple models the most basic concepts of heat transfer, fluid mechanics, and thermodynamics as mentioned in this paper.

Thermophysical properties of high porosity metal foams
TL;DR: In this article, the effective thermal conductivity (ke), permeability (K), and inertial coefficient (f) of high porosity metal foams were derived by considering a circular blob of metal at the intersection of two fibers.

Momentum transfer at the boundary between a porous medium and a homogeneous fluid-I. Theoretical development
TL;DR: In this paper, the authors developed a jump condition based on the non-local form of the volume averaged momentum equation, which produces a jump in the stress but not in the velocity, and this has important consequences for heat transfer processes.

The Cheng–Minkowycz problem for natural convective boundary-layer flow in a porous medium saturated by a nanofluid
TL;DR: In this article, the Cheng-Minkowycz problem of natural convection past a vertical plate, in a porous medium saturated by a nanofluid, is studied analytically.
