Full-stack, multiscale modelling of the rheology and fluid mechanics of complex fluids.
Complex fluids — polymer solutions, suspensions, slurries, sprays — are everywhere in industry and notoriously hard to predict. Their flow behaviour emerges from a strong two-way coupling between the macroscopic flow and an evolving microstructure, spanning an enormous range of length and time scales.
The CReSI Lab builds models across that whole stack, from the molecular and particle scale up to the continuum flow. Our aim is a full-stack description that connects micromechanics to macroscopic rheology and to process-scale flows, so that the design of sustainable industrial processes for handling complex fluids can rest on predictive computation rather than empiricism. We approach constitutive modelling and non-equilibrium thermodynamics through an information-theoretic lens.
Tensorial, thixo-elasto-visco-plastic models that capture the coupling between flow and microstructure in viscoelastic and yield-stress fluids.
Brownian dynamics of polymers and suspensions, from single molecules to concentrated systems, resolving the physics that sets the rheology.
Extensional rheology, liquid bridges, and the stretching and breakup of complex-fluid filaments.
The rheology and continuum description of self-propelled particles and active suspensions.
