| Abstract: |
Viscosity of fluids has been considered as one of the most important parameters affecting the mixing process at the molecular scale. The aim of the paper is to investigate the influence of viscosity on micro-mixing of Non-Newtonian fluid by using fast parallel reactions and, different concentrations of HEC. The experiment was carried out in stirred tank of 0.476 m diameter agitated by a Rushton turbine. It has been confirmed that precipitation reaction of NaOH and CuSO4 as one of the two parallel competing reactions, is very efficient for such a study. This was confirmed as by product (XQ) of parallel reactions varied with the feed time, stirred speed, feed position, viscosity and Dav. The experimental results show that; XQ as a measure of the amount of by-product was increased with increasing HEC concentration and, decreases from position (1) to position (2) from position of low to high local energy dissipation rates and, also decreases with increasing agitation speed. And, the experimental results confirmed that, how much the viscosity has a direct influence on the micro mixing of Non-Newtonian fluid. |
