Abstract
En 中文
A computational fluid dynamics (CFD) based investigation of structured packing geometry was performed for gas phase hydrodynamic and mass transfer performance. The computational results were validated with experimental data with a robust mass transfer methodology for the gas-phase resistance identified through pipe flow simulations. The methodology was then applied to structured packing simulations for a variety of industrially relevant geometries. The mass transfer predictions agreed to within five percent of pilot-scale experimental data for standard commercial packings. The geometry of structured packing was studied by systematically changing the specific packing area, channel inclination angle, and channel opening angle to determine the geometry which produced a high degree of mass transfer or a low pressure drop.
