Fluid mechanics and design aspects of a novel oscillatory flow screening mesore...

A novel, continuous, oscillatory flow screening mesoreactor, composed of tubes with smooth periodic constrictions, is presented as a new option for small-scale reaction engineering applications, particularly those involving the screening of solid catalysts. Experimental studies using particle image velocimetry have demonstrated that this reactor provides good fluid mixing, and is able to suspend catalyst partic...

This paper is concernedwith the fluidmechanics andmixing performance of a novel oscillatory flow screening reactor. Using fibre optic probes, a mixing coefficient k_m is determinedfor the system as a function of the applied fluid oscillation frequency and amplitud. In a continuous operation mean residence time and a backmixing coefficient g are estimatedas a function of the oscillation conditions. Finally, in o...

Residence times and mixing of a novel continuous oscillatory flow meso reactor

A novel meso reactor based on oscillatory flow technology (Harvey et al., 2001) has been recently presented in Harvey et al. (2003) as a new technology for reaction engineering and particle suspension applications. Due to the demonstrated enhanced performances for fluid micro mixing and suspension of catalyst beads and to the small volume of the reactor, this novel miniature reactor is suitable for applications...

Enhanced mass transfer rates of a novel oscillatory flow screening reactor

A novel continuous small-scale reactor based on the oscillatory flow technology (Harvey et al 2001) is being developed for application to specialist chemical manufacture and high throughput continuous screening (Harvey et al 2003). This novel reactor is able to perform continuous multiphase reactions, including those involving the suspension of catalyst beads. Extensive potential use in chemistry, biological an...

The use of fibre optic probes for flow monitoring within a small-scale tube

This paper demonstrates the effectiveness of using fibre optic micro-probes for the measurement of dispersion and mixing in continuous flow within small-scale tubes under oscillatory flow conditions. The experimental data was modelled and compared either by three different well-known non-ideal models: a) tanks-inseries (with no backflow); b) differential backmixing; c) stagewise backmixing, and by one two-param...
