On the influence of liquid distribution on heat transfer parameters in trickle bed systems

The aim of this work is to analyse experimental results on radial heat transfer in a packed bed column with cocurrent downflow of liquid and gas, focused on the influence of radial liquid distribution and column to particle diameter ratio. For this purpose, two kinds of measurements were carried out...
