Study of the temperature effect of shear thickening fluid

This paper presents the study of temperature effect on a shear thickening fluid made of ethylene glycol and fumed silica with a 20% weight fraction. Four typical temperatures, ranging from 20°C to 80°C, were selected to study the shear rate dependence of viscosity. The temperature tests show that the high temperature increases the critical shear rate and lower the shear thickening ratio. A viscosity function is proposed to represent the three characteristic regions in typical shear thickening fluid and to predict the viscosity at different temperatures.
