摘要
采用Fluent软件对鼓泡流态化反应器内气液两相流的流场进行了数值模拟,分别计算了三种不同工况下的流场分布状况。模拟结果表明:增大气体喷射速度和喷射管的插入深度都可以使气液两相混合更加充分,流场内较易形成涡旋结构,达到稳定流场的时间也比较短。
In this paper,the flow field of gas-liquid two-phase flow in a bubble fluidized reactor is simulated by Fluent.The flow field distribution under three different operating conditions is calculated.The simulated results are as follow:the mixture of gas-liquid two-phase can become more sufficient as adding the jet velocity of gas and the immerged depth of jet pipe,and the eddy forms more easily,the time of obtaining steady flow field is shortened.
