Modeling of Gas Flow through a Granular Bed of a Thermal Storage Phase-Change Material

Resumo

A mathematical model and a numerical method for description of time-dependent gas flows through granular thermal storage phase-change materials (PCMs) have been proposed. Such granular PCMs are modeled as porous solid–solid phase-change media using the methods of heterogeneous continuum mechanics without detailing the processes inside individual particles. The calculation results are compared with the experimental measurements to show their good agreement with each other.
