Influence Of Viscosity On The Micromixing Of Non-Newtonian Fluid In A Stirred Tank

Mechanically agitated reactors are widely used in many industrial processes, such as chemical, pharmacy, food, petroleum, et al.. Micromixing refers to the process of material homogenization from Kolmogorov scale to molecular scale after turbulent diffusion. Micromixing has a great influence on the product distribution of complicated fast reactions.Though micromixing has been studied intensively in the last decade, most of the researches have been carried out in small-scale reactors. It is difficult to investigate the effect of tank geometry on micromixng in such small scale reactors. Little attention has been paid to the Non-Newtonian fluid system characteristics of micromixing in tank with high viscosity.The influence of viscosity on the micromixing of non-Newtonian fluid was investigated by using two parallel competing reactions, cupric sulfate and sodium hydroxide competing with alkaline hydrolysis of ethyl chloroacetate, which were improved and successfully applied in the viscous fluid as working reactions. The experiments were carried out in a stirred tank...
