A Mesoscopic Particle-based Method for Nematohydrodynamics
Research on topological microfluidic transport, the dynamics of self-assembly in liquid crystals and so-called hypercomplex fluids requires versatile and numerically efficient mesoscopic algorithms. I will describe a multi-particle collision dynamics (MPCD) based algorithm for simulating fluctuating nematohydrodynamics, the flow of liquid crystals. This nematic-MPCD method successfully reproduces the features of a nematic liquid crystal, including an isotropic-nematic phase transition, intrinsic elastic coefficients, tumbling and shear alignment regimes, and defect dynamics. Though simple, it represents a promising tool for modelling defect dynamics within porous media, the interactions of colloids, self-propelled particles and dispersed carbon fibres within liquid crystal media. I demonstrate of the method can be extended to simulate active fluids, which represent an exciting path for studying intrinsically out-of-equilibrium phenomena with direct ramifications for biological systems. Active MPCD simulations exhibit the hallmarks of active nematic fluids, including the formation of lines of kinks in the orientation field and the onset of mesoscale trubulence via the unzipping of these lines through the creation of topological defects.

UKRI Deadlines
Due to the implementation of a new UKRI funding system (TFS) there will be a fixed quarterly deadlines for some grants which would previously have been on open calls, this is to allow necessary system amendments and updates.
The first deadline after implementation will be 28th September 2023 and applies to those calls listed below:
