Apparatus for measuring the effective thermal conductivity of packed bed of aggregates

Abstract

Systems and methods for measuring the effective thermal conductivity of aggregate packed beds are described. Systems and methods may include an apparatus comprising a first assembly, a second assembly, and a cylindrical insulator. The first assembly may include a first faucet, a first brass cover, a first heat exchanger body, and a first aluminum plate. The second assembly may include a second faucet, a second brass cover, a second heat exchanger body, and a second aluminum plate. The first assembly and the second assembly may be placed into opposite ends of the cylindrical insulator. Aggregates may be placed inside the cylindrical insulator between the first and second assemblies. Temperature may be measured at a variety of points of contact on the two faces of a low thermal conductivity plate, and heat flux and effective thermal conductivity of packed bed of aggregates may be calculated.
