Abstract

Granular materials offer many advantages which qualify them for use as heat transfer medium and heat storage material in solar thermal power plants and industrial processes. Moving bed heat exchangers (MBHE) with horizontal tubes are favorable to extract thermal energy from hot granular materials. Their thermal performance is determined by a complex granular flow field in the device. This calls for accurate simulation models on which novel design tools can be based. In this work a continuum model is developed to calculate the granular flow field and heat transport in a MBHE. The model is supplemented by simulations using a discrete particle model which provides insight into flow phenomena occuring on the particle level.
