Suspensions in viscoelastic media
My PhD project is on modelling suspensions in viscoelastic media with Dr Helen Wilson at UCL. I like to think of this project as asking “if I have shampoo with glitter in it, and I shake the shampoo, where does the glitter go?”. Many industries use non-Newtonian liquids with particles in them (think paint, adhesives and even blood), and I’m looking at how these particles move, whether we can model certain non-Newtonian fluids using these suspensions, and whether I can explain some odd phenomena observed when dropping things through these suspensions. I do this all using computer code based on a procedure called Stokesian Dynamics.
Notes from my work:
- Corrections to Jeffrey & Onishi (1984) (or generating, from scratch, near-field asymptotic forms of scalar resistance functions in Stokesian dynamics)
My masters project was The fluid dynamics of chocolate fountains, also under the supervision of Dr Helen Wilson. A tasty study into the behaviour of non-Newtonian fluids in three different geometries, the project is linked to below. Since then I have given popular mathematics talks on chocolate fountains many times over all over the country!
