新型错位桨反应器内黏性流体流动混合优化
Optimization of viscous fluid flow and mixing in a novel misaligned paddle agitator
摘要
Abstract
This study introduced an anchor-simple-ribbon misaligned paddle agitator,which was developed through the adjustment and combination of various agitator designs.The flow and mixing characteristics of this agitator were examined using computational fluid dynamics analysis,with its geometry refined based on machine learning predictions.Results indicate that impeller diameter is the primary factor influencing the power number,while bottom clearance and blade spacing exert minimal impact on it.As the impeller diameter increases,both local disturbance and the overall circulation capacity of the impeller improve,leading to reduced mixing time.Furthermore,mixing time decreases as bottom clearance increases;although blade spacing has negligible effects within a certain range,it significantly influences mixing time once exceeding a critical threshold.A comparative analysis of three different machine learning models reveals that the gradient boosting model is most suitable for this application.关键词
