Temperature Distribution Analysis of Viscoelastic Fluid Stirred By Single Triangular Rotor

During rubber manufacturing, rubber is mixed with compounding agents through kneading process. Kneading results to generation of very high shear heat. High heat sometime leads to burnt and low quality rubber. Also this high heat changes rubber from solid to viscoelastic form. In order to analyze temperature distribution of viscoelastic fluid, CMC (Carboxyl Methyl Cellulose) have been prepared. The solution was kneaded using simple single triangular rotor. Compared to rubber, shear heat in CMC solution is very low. Thus to compensate shear heat, external heater has been used. Temperature measurement was done using LIF (Laser Induced Fluorescence) technique. Kneading was done under different rotor speed and it was found that higher rotor speed resulted into proper temperature distribution. Beside, at the tip of the rotor, high temperature fluid was accumulated. When compared to normal viscous fluid (Glycerol), CMC showed different shape of temperature field at rotor`s tip.
