从泰勒方程出发[Taylor，G.一、程序R。秒伦敦系，A 138，41-48（1932）]对于非常稀的乳状液的粘度，使用有效介质方法发展了浓乳状液的新粘度方程。根据本文推导的方程，浓乳液的粘度随分散相体积分数和分散相与连续相粘度比（K）的增大而增大。在K -> co的限制下，方程简化为众所周知的固液悬浮液的公式。根据大量的浓乳液实验数据对所提出的方程进行了评估，所述浓乳液涵盖了宽范围的分散相与连续相粘度比（3.87 × 10（-4）小于或等于K小于或等于3.25 × 10（5））。(C)2001年，流变学学会。
Starting from the Taylor equation [Taylor, G. I., Proc. R. Sec. London Ser., A 138, 41-48 (1932)] for the viscosity of very dilute emulsions, new viscosity equations are developed for concentrated emulsions using the effective medium approach. According to the equations derived in the paper, the viscosity of concentrated emulsions increases with the increases in the volume fraction of the dispersed phase and the viscosity ratio (K) of the dispersed phase to the continuous phase. In the limit of K --> co, the equations reduce to the well-known formulas for solids-in-liquid suspensions. The proposed equations are evaluated in light of a large body of experimental data for concentrated emulsions, covering a broad range of dispersed-phase to continuous-phase viscosity ratio (3.87 x 10(-4) less than or equal to K less than or equal to 3.25 x 10(5)).
