Abstract
In this publication, experimental results for the radial multiphase thermal conductivity and the wall heat transfer coefficient of different ceramic sponges as column internals for trickle beds are presented. The experiments were performed in co-current mode with the fluids water and air. The material, porosity and cell density of the sponges were varied. A strong influence of the superficial liquid velocity and of the cell density on the radial multiphase thermal conductivity is found. Dimensionless correlations of the experimental data are given.
