The influence of the addition of a drag reducing agent (100 ppm PAA) to a pure liquid (water) in a stirred vessel has been studied. The vessel was stirred with two types of agitators, a Rushton turbine and an axial A310 impeller. This study was meant

This work is aimed at investigating the fluid dynamic characteristics of a stirred tank of standard geometry for the dispersion of organics in water. Two different aspects have been considered. Firstly, the dispersion conditions at different impeller

The features of solids concentration distribution were investigated in two baffled vessels of different scale. The vessels were of high aspect ratio and were stirred with multiple PBTs (pitched blade turbines). Both steady- and unsteady-state experim

The distribution of dilute, mixed solids in Newtonian fluids in a baffled vessel stirred with multiple impellers has been studied experimentally and simulated by means of Computational Fluid Dynamics. For the sake of experimental simplicity, fraction

In this work, a novel stirred tank for the production of biohydrogen by fermentation of organic wastes is presented. The bioreactor is designed for ensuring effective mixing of the liquid phase, full contact between the substrate and the biofilm and

Mixing time is a key parameter for evaluating the blending effectiveness of stirred tanks but, in contrast with the case of single impeller configurations, a general purpose correlation for multiple impeller geometries is not available to date. In th

The gas behaviour was studied in a gas-liquid reactor stirred with multiple turbines. Triple PBTs pumping either down or up and BT-6's were used. The behaviour of coalescing (water) and non-coalescing (sodium sulphate solution) systems was investigat
