摘要
搅拌桨的循环流量是评价搅拌混合效果和搅拌能力强弱的关键参数,也是桨叶结构设计优化的重要依据。但是,循环流量在试验室内无法准确测量,搅拌釜内工况恶劣,专业的数据检测仪器的安装难度大、成本高,难以保证检测能力和准确性。针对以上问题,对比三叶推进式桨的经验计算与数值模拟计算结果,验证数值模拟的准确性,提出对于排出性能缺乏经验参考的搅拌桨可以采用数值模拟预测,从而为搅拌桨的设计选型提供依据。
The circulating flow rate of the impeller is the key parameter to evaluate the mixing effect and mixing capacity,and it is also an important basis for the design and optimization of the impeller structure.However,the circulating flow rate cannot be accurately measured in the test room,the working conditions in the stirred tank are harsh,the installation of professional data detection instruments is difficult,the cost is high,and the detection ability and accuracy are difficult to ensure.In view of the above problems,comparing the results of the empirical calculation and numerical simulation of the three-blade propeller,the accuracy of the numerical simulation is verified,and it is proposed that the impeller with the lack of empirical reference can be predicted by numerical simulation,which provides a basis for the design and selection of the impeller.
