Abstract
Ozone decomposition in the riser is simulated with computational fluid dynamics in order to explore the scale-up effect on the chemical reaction performance. Glicksman’s full and simplified scaling rules are used to build two 1:3 scaled-up risers. The variation of cluster features during the scale-up process is approached with the energy minimization multiscale drag model. The comparison of axial and radial ozone concentrations between three cases indicates that the scale-up process exhibits less uniformity in the radial ozone distribution. The variation of cluster effect during the scale-up process has an evident effect on the gas–solid contact efficiency. The overall gas–solid contact efficiency is improved during the scale-up process with full set scaling rules.
