How is Toothpaste made?

The manufacturing process for toothpaste involves mixing together several fluid and solid components to create the non-Newtonian polymer used to clean your teeth. Since water cannot be used, the mixing process is extremely complex and the source for many interesting physical phenomena which are studied via experiments and computer simulations. Research by Simona Migliozzi at University College London. Interview with University of Oxford Mathematician Dr Tom Crawford. This video is part of a collaboration between FYFD and the Journal of Fluid Mechanics featuring a series of interviews with researchers from the APS DFD 2017 conference.

Migliozzi et al. "Experimental and computational fluid dynamics studies of mixing of complex oral health products" http://meetings.aps.org/link/BAPS.201... Highly viscous non-Newtonian fluids are largely used in the manufacturing of specialized oral care products. Mixing often takes place in mechanically stirred vessels where the flow fields and mixing times depend on the geometric configuration and the fluid physical properties. In this research, we study the mixing performance of complex non-Newtonian fluids using Computational Fluid Dynamics models and validate them against experimental laser-based optical techniques. To this aim, we developed a scaled-down version of an industrial mixer. As test fluids, we used mixtures of glycerol and a Carbomer gel. The viscosities of the mixtures against shear rate at different temperatures and phase ratios were measured and found to be well described by the Carreau model. The numerical results were compared against experimental measurements of velocity fields from Particle Image Velocimetry (PIV) and concentration profiles from Planar Laser Induced Fluorescence (PLIF).
