Modeling of Granule Filling in Wall Gap for Estimation of Role of Thermal Convection


Development of new, more efficient thermal insulation materials is a key to reduction of heat losses and contribution to greenhouse gas emissions. New materials – Izoprok and Izopearl – are developed by Thermeko LLC. In this research a modelling approach is developed for evaluation of spatial distribution of disperse insulation material. Computational fluid dynamics approach is also used to estimate role of different heat transfer phenomena in such porous mixture. Modelling results show that thermal convection plays small role in heat transfer despite large fraction of air within material pores.
