Confinement induced three-dimensional trajectories of microswimmers in rectangular channels
Byjesh N. Radhakrishnan, Ahana Purushothaman, Ranabir Dey +1
We study the trajectories of a model microorganism inside three-dimensional channels with square and rectangular cross-sections. Using (i) numerical simulations based on lattice-Bo…
Viscoelastic confinement induces periodic flow reversals in active nematics
Francesco Mori, Saraswat Bhattacharyya, Julia M. Yeomans +1
We use linear stability analysis and hybrid lattice Boltzmann simulations to study the dynamical behaviour of an active nematic confined in a channel made of viscoelastic material.…
Scalar transport from deformed drops: the singular role of streamline topology
Pavan Kumar Singeetham, Sumesh P Thampi, Ganesh Subramanian
We examine scalar transport from a neutrally buoyant drop, in an ambient planar extensional flow, in the limit of a dominant drop phase resistance. For this interior problem, we co…
