- Abstract
Computational fluid dynamics (CFD) is used to study the gas-particle heat transfer in gas-phase olefin polymerizations. Particularly, the effects of particle rotation on the gas-particle heat transfer coefficient and internal particle temperatures are evaluated, showing that particle rotation can exert a significant impact on observed temperature profiles, so that this effect should not be neglected during detailed CFD process simulations. As a consequence, particle rotation can lead to particle cooling and development of spherical gradient symmetry, validating the use of simpler modeling schemes that are based on reaction-diffusion in symmetrical spherical geometry.
