摘要
在直径为 1 86mm的立式搅拌釜内 ,利用热电偶—温差法测量了两层组合桨搅拌釜内的液相混合时间 ,试验中采用的搅拌桨有直叶圆盘涡轮和斜叶涡轮 (上推式斜叶涡轮 PTU和下压式斜叶涡轮 PTD) ;根据激光多谱勒测速仪对流场的测量结果 ,提出了一种新的二维单元串联模型 ,用该模型对两层组合桨搅拌釜内的混合过程进行了模拟 ,发现模拟值和实验值吻合较好。
Mixing times in a vessel agitated by two impellers were determined using temperature difference technology measured by thermocouples.Some impellers were employed,such as straight blade Disc turbines and pitched blade turbine.A new cells in series model without model parameter needed to be regressed was put forward and used to simulate the mixing process in a stirred vessel.Comparisons of predicted values of mixing times according to the present model with experimental data in the paper showed good agreement.
