A three-dimensional computational fluid dynamic model has been developed to investigate the efficiency of a direct-contact metal recovery condenser as a function of the operating conditions ( droplet diameters, droplet injection rate) and overall condenser dimensions. The Eulerian-Lagrangian approach is used to model the condenser, where liquid zinc droplets are injected into a zinc vapor laden gas stream so that zinc vapor can directly condense on the droplets. The results show that there exists an optimum droplet injection rate that maximizes condenser efficiency  相似文献
