Abstract
A study was made of the rheological behavior of dilatant fluids. It was found that such behavior is particularly sensitive to size, shape, and surface characteristics of particles used in dilatant systems. Dilatant behavior was found to take place with a number of different suspensions of corn starch in various fluids. These fluids were ethylene glycol, ethylene glycol-glycerine, ethylene glycol-glycerine-water, and ethylene glycol-water. The power law held for flow curves of these fluids from 20 to 250 sec−1. Effect of temperature on power-law parameters was determined. It was found that n, flow behavior index, was relatively insensitive to temperature while K, consistency index, was a function of temperature according to an Arrhenius relation. The power-law parameter relation to suspension concentration was also determined. It was found that n increased with increasing concentration while K decreased with increasing concentration.
