Advances in Fluid Mixing
What is on the prospect in terms of fluid mixing technology? How will the fluid mixing technology of tomorrow be more effective/ efficient than the fluid mixing technology of today?
Fluid mixing technology has made rapid advances in recent times. New impellers designs have ensured that mixing equipment are able to deliver precisely to the process requirements. These improvements have been catalyzed by advances in technologies such as Computational Fluid Dynamics (CFD), Digital Particle Image Velocimetry (DPIV), Laser Doppler Anemometry (LDA) and Laser Induced Fluorescence (LIF).
- CFD provides detailed analysis of fluid flow early in the development process. The effects of vessel geometry and internals such as baffles can be factored into the system design. Mixing problems, such as low-velocity areas, circulation zones, staging and anomalies in the fluid flow and other potential problems can be identified and quickly resolved, instead of adopting the conventional and time consuming trial and error process.
- Using DPIV technology, it is possible to measure the fluid velocity field in the mixing vessel at all points almost instantaneously thereby making it possible to study large-scale, time-dependent phenomena which are responsible for the mixing process.
- LDA is probably the best method of non-intrusively determining mean velocity and turbulence data to high level of accuracy. This information may be used with CFD to accurately determine the flow in the mixing vessel.
- LIF is a measurement technique, which provides both qualitative and quantitative assessment of mixing.
The development and implementation of these technologies shall minimize the unpredictability associated with the mixing performance.
