This semester 1 module introduces fundamentals of liquid mixing in industrial systems and covers both the mechanisms and their application within the chemical and process industries. The module considers the mixing of single phase liquids and also the introduction of additional (immiscible) phases.
The module introduces laminar and turbulent mixing mechanisms and how these are exploited in different process equipment, namely stirred vessel, pipes, static and jet mixers. Ways of characterising the degree of mixedness or dispersion are also considered. The module covers how mixing is affected by scale up of process equipment and how this may be overcome, by consideration of different scale-up methodologies. Both Newtonian and non-Newtonian fluids are considered.
Finally, the module considers how mixing of a separate immiscible phase, gas, solid, or liquid may be performed, focussing on chemical engineering applications in stirred tanks and static mixers.
