摘要

对泡沫的流变特性进行了实验研究.结果表明

泡沫为典型的拟塑性流体

其流变模式为μ_a=Kγ~(n-1).在(?)=40%～90%内

得到K=1866.84(?)~(3.094)

n=0.3866exp(1.591(?)-1.108(?)~2)此外

泡沫的表观粘度还受起泡剂的种类、浓度、泡沫的大小、外界温度等因素的影响.

Abstract

The foam rheological properties are studied experimentally in this paper. Foam behaves like a pseudoplastic fluid with a viscosity inversely proportional to shear rate. Its apparent viscosity is affected strongly by foam quality. From experimental results

the rheological parameters

K and n

are determined and two correlations are obtained: Additionally

the rheological properties of foam are related with the type and concentration of foaming agents

diameter of foam

temperature

etc.
