TLDR
In this article, an empirischen Anpassungsparameter, der nur von der Form der Partikel abhangt und aus in der Literatur veroffentlichten Meswerten bestimmt wird, is introduced.Abstract:
Die effektive Warmeleitfahigkeit nicht durchstromter Schuttungen hangt stark von der Art der Beruhrung der Partikel ab; sie ist z. B. bei Kugeln und Zylindern unterschiedlich. Aus einem einfachen Modell werden Gleichungen entwickelt, die auser den Warmeleitfahigkeiten der fluiden Phase und des Feststoffs die Porositat der Schuttung berucksichtigen. Die Gleichungen enthalten einen empirischen Anpassungsparameter, der nur von der Form der Partikel abhangt und aus in der Literatur veroffentlichten Meswerten bestimmt wird.read more

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.

A review of correlations to model the packing structure and effective thermal conductivity in packed beds of mono-sized spherical particles
TL;DR: In this article, a review of the literature describing the packing structure and effective thermal conductivity of randomly packed beds consisting of mono-sized particles is presented, with particular attention paid to the packing structures (porosity, coordination number, and contact angles) and heat transfer.
