摘要:
采用多重参考系法(MRF)及标准k-ε模型对工业中广泛应用的45°折叶涡轮桨搅拌槽内的搅拌特性进行模拟,考察不同监测点对混合效果的响应情况,发现不同监测点的响应出现明显的差别.对搅拌桨距槽底距离变化时,槽内搅拌流型以及速度矢量的分布和功率消耗情况进行模拟研究,结果表明:当C/T为0.278时,槽内流型发生转变;当流型转变时,搅拌桨消耗功率达到最低.
Abstract:

The multiple reference frame method (MRF) and standard k-ε model were used to simulate the stirring characteristics in the 45° folding blade turbine stirring tank widely used in industry, and the response of different monitoring points to the mixing effect was investigated, and obvious differences were found in the response of different monitoring points. The simulation study of the stirring flow pattern in the tank and the distribution and power consumption of the velocity vector when the distance from the bottom of the mixing paddle is changed, and the results show that when the C/T is 0.278, the flow pattern in the tank changes. When the flow pattern is changed, the power consumption of the impeller reaches a minimum.
