非牛顿液体流变模式的研究

RESEARCH ON NON NEWTONIAN LIQUID RHEOLOGICAL MODE

对国内外常用的几种流变模式进行了分析和评价，指出了它们的特点和不足之处。在总结和归纳的基础上，提出了一个带静切应力的三参数多项幂律模式（简称Ｌ—Ｍ模式）。研究还从该模式的本构方程出发，推导出流变参数及有关水力参数计算式，并应用大量的泥浆及水泥浆试验资料和计算数据，对比和分析了各流变模式的适应范围及精确程度，进而证明了Ｌ—Ｍ、Ｈ—Ｂ流变模式具有适应范围广、准确性高的特点。

A three parameter polynomial power law mode (i.e.L—M mode)with static shearing stress is proposed out after analysing and assessing several rheological modes commonly used at home and abroad.Starting from researching the constitutive equation of the mode,the rheological parameters and the calculation formula of the relevant hydraulic parameters are derived.The adoptive scope and accuracy of each rheological modes are contrasted and analysed by plenty of experiment and calculation data of mud and slurry.
