Abstract: The unevenness of temperature profile of highly viscous liquid in an agitated vessel was described with a non-dimensional variable Analyzing the non-dimensional differential equation tor the laminar flow of the agitated liquid with helical ribbon impeller yielded the functional relation O = f(Pe,Ec/Re) Regression of the Newtonian and pseudoplastic fluids temperatures measured in the agitated vessel resulted in the correlations for five types of combined impellers such as helical ribbon-anchor, helical ribbon-helical screw-anchor etc. It is found that in -out helical ribbon anchor ( I ) impeller is the best one.

摘要： 本文提出用无因次量描述搅拌槽中高粘度液体温度场的不均匀性.对螺带桨搅拌液体作层流时的无因次微分方程进行分析得到(?)=f(Pe、Ec/Re).用实测的牛顿流体及假塑性流体槽液温度回归获得螺带-锚及螺带-螺旋轴-锚等五种组合桨(?)的关联式.内外螺带-锚(Ⅰ)桨是五种桨中最优良的桨型.
