钛渣流态化氯化流动特性的数值模拟
Numerical simulation for flow characterisitcs in titanium slag fluidization
摘要
Abstract
The flow characteristics of chlorination of titanium slag in a fluidized bed are studied based on two-fluid model combined with physical properties of titanium slag with Fluent under different critical fluidizing velocities.Numerical results indicate that the modifier formula by Grace is more suitable for calculating the minimum fluidization velocity of chlorination of titanium slag.Furthermore,it also shows that,under minimum fluidization velocity,emulsion phase emerges first in the bed,and then some small bubbles take place,while under complete fluidization velocity,slugging processes at the beginning,and then it turns to be complete fluidization.关键词
