摘要: 实验测定了双轴表面更新型卧式釜中采用三种不同形式的搅拌桨、多种桨间距、广泛的粘度范围内牛顿流体和非牛顿流体的功率特性;统一关联了牛顿流体与非牛顿流体的搅拌功耗,得到:N_PRe=C(l/D_f)~(-1)(V_L/V~*)~D式中的C、D是搅拌桨的结构参数.实验结果还表明,该装置的Metzner常数是转速的函数.

Abstract: The power characteristics were investigated with highly viscous Newtonian and non-Newtonian fluids in a surface-renewal type reactor under the conditions of three kinds of impeller. The results were correlated by means of the Metzners constant. It was obtained that
