- Description
- This study experimentally investigates the application of a solid-liquid micro-fluidised bed as a micro-mixing device. The experiments were performed in a borosilicate capillary tube with an internal diameter of 1.2 mm (i.e. near the upper-limit dimension of a micro-fluidic system) using borosilicate particles with a mean diameter of 98 μm. Refractive index matching technique using sodium iodide solution was employed to achieve a transparent fluidised bed. Mixing performance of the micro-fluidised bed in terms of mixing time was investigated using dye dilution technique. The preliminary results showed that the mixing time in a micro-fluidised bed can be reduced by 1/8th of the time required for liquid-liquid mixing in a capillary tube. The rise in the mixing rate was considered to be due to secondary transversal mass transport caused by passive chaotic advection.
