Thomas C. Sykes


I am a PhD student in fluid dynamics, with research interests in the droplet dynamics and complex fluids.

Research interests

My primary research interests lie in droplet dynamics, especially coalescence and interactions with a solid substrate (wetting, impact, etc.). I study these flows using both numerical simulations (usually with open-source tools such as OpenFOAM) and physical experiments (generally high speed imaging), working across various disciplines and departments. My work generally focuses on fundamental fluid dynamics, but has close ties to applications from microfluidics to next-generation additive manufacturing techniques (e.g. reactive inkjet printing).

I am also interested in complex fluids, such as colloidal suspensions. For example, I have worked on colloidal sedimentation under centrifugal force with Procter and Gamble (P&G), developing an improved mathematical model for these flows (validated against highly controlled experiments and published in Physics of Fluids).

I have previously worked on methods for linking anonymised data records and Monte Carlo Methods in statistical physics.
