Effective conductivity of regularly packed spheres - Basic cell model with constriction
Abstract
Analytical solutions for conduction in basic cells of regularly packed spheres are obtained. The basic cells are shown to consist of a number of effective contact regions. The influence of packing, mechanical load, and gas pressure is determined. Experimental results for a single contact region, and for an FCC basic cell, are in excellent agreement with the analytical results at all mechanical loads and gas pressures for air, argon, and helium.
