摘要
为了研究搅拌槽的功率及其影响因素,分别采用Bachjbhob算图、永田进治公式、流场数值模拟的方法计算搅拌槽功率。首先采用Mixsim软件建立搅拌槽模型,然后将其导入至FLUENT软件中进行三维流场模拟分析,最后通过Mixsim软件计算搅拌槽的功率,并且对影响其功率的因素进行分析。分析结果表明:3种功率计算方法的结果基本一致;在一定的范围内,随着搅拌槽的浆叶宽度、数量的增加,浆叶角度的增大,搅拌槽的功率也随之增大,液层高度对其功率影响较小。
In order to research the power of the stirring tank and its influencing factors, Bachjbhob chart, Nagata Shinji formula and numerical simulation method of the flow field were respectively used to calculate the power of the stirring tank. Firstly Mixsim software was applied to build the model of the stirring tank, and then the model was imported into FLUENT to simulate and analyze 3D flow field of the stirring tank. Finally, Mixsim software was applied to calculate the power of the stirring tank, and the factors affecting the power of the stirring tank was analyzed. The analysis results showed that： results obtained from three methods of power calculation were basically identical; during a certain range, with the increase in width of the blade, numberof the blade and angle of the blade, the power of the stirring tank increased, while the liquid level had a little influence on the power of the stirring tank.
