Unilever creates products that enrich and improve people’s lives today while aiming to make sustainable living commonplace. Within Unilever’s portfolio, products with a range of microstructures and rheologies can be found.
The proposed research project aims to improve our understanding of the processing challenges of lamellar fluids. The manufacture of these fluids is achieved through the sequential addition of raw materials in a defined order, at controlled temperature, and mix speeds.
Two attributes vary throughout the process: fluid level and rheological properties. These attributes impact mixing intensity and flow characteristics within the vessel, thereby affecting product quality and energy requirements.
Scale-up of the manufacturing process is thus challenging and not amenable to general dimensionless number/geometrical similitude approaches. The proposed project aims to explore the effects of fluid level and rheological properties on process scale-up for lamellar fluids.
The experimental approach will focus on the use of torque measurements, the development of power draw expressions, and characterisation techniques such as PEPT and PIV.
In addition, the project will explore CFD to identify an approach that will allow the user to track the evolution of the fluid level in the vessel and product rheology through the process, using experimental results for validation.
