Abstract
The flow fields of dual-layer impellers in the agitation tank was numerical stimulated by the fluent software .The influence of the different interlayer spaces on the speed field were studied .The results show that for the dual-layer stirring paddle ,w hen the distance of the impellers is smaller than the stirring paddle diameter ,the flow by the dual-layer stirring paddle could connect with each other , therefore its stirring effect is good .When the distance becomes longer ,flow of the dual-layer paddels form own cycle ,the fluid in the agitation tank flows partition .There is a best distance between the paddels ,which would be a little smaller than the stirring paddle diameter .关键词
