Fluid Shearing for Enhanced Collisions and Accelerated Reactions

Abstract eng:
The aim of this project is to explain the fluid motion and maximise the performance of the Vortex Fluidic Device, a rapidly rotating tube with pipettes feeding liquid reactants to the base of the tube. It is a novel ‘greener’ technology for industrial applications such as pharmaceutical production and protein folding. The problem is approached according to the stages of fluid spreading, with the most promising area being at the bottom of the hemispherical tube as the fluid reaches the solid surface and spreads along the walls. The parameters that affect the spreading are defined and their role is explored theoretically and experimentally with respect to the geometry of the tube. The spreading pattern is explained and the optimum fluid volume, release height and rotation rate are established for both a flat disk and a hemispherical bowl.
