Multiphase impeller stirred tank reactors enhance mixing of reacting species used in a variety of chemical industries. These reactors have been studied based on Computational Fluid Dynamics (CFD) that can be used in the analysis, design and scale up of these reactors. Most of the researches done in this area are limited to single phase reactors, and a few remaining two phase flow investigat...

1. Better bacterial inactivation was observed with higher ultraviolet (UV) doses. There is a need for better tank configuration (hydraulic performance) to ensure proper water circulation or a need to suppress microbial recovery. Addition of titanium dioxide (TiO2) during UV irradiation was effective in controlling microbial recovery. 2. Higher water temperature enhanced the fouling rate on quar...

Abstract The key for improving the mixing efficiency of pseudoplastic fluids is to enhance chaotic degree in flow field. xanthan gum solution was used study characteristics and performance a stirred tank with impeller perturbed six-bent-bladed turbine. Based on velocity time series collected by experiment particle image velocimetry (PIV), distributions largest Lyapunov exponent (LLE) Kolmogorov...
