Abstract
In this paper, detailed analyses of some bulk materials and their flow properties related with the operation with porous heat exchanger wall types are presented. A focus is on granular media and their properties. Investigations with respect to attrition and abrasion have been performed to identify the most suitable granular product in combination with different wall materials. Tested products are alumina grinding balls, sintered bauxite, fused silica and silicon carbide on the ceramic side, quartz sand and flints, basalt and normal corundum on the natural products side.
