Travelling-wave spatially periodic forcing of asymmetric binary mixtures
Lennon O'Naraigh
We study travelling-wave spatially periodic solutions of a forced Cahn-Hilliard equation. This is a model for phase separation of a binary mixture, subject to external forcing. We…
Advection of nematic liquid crystals by chaotic flow
Lennon O'Naraigh
Consideration is given to the effects of inhomogeneous shear flow (both regular and chaotic) on nematic liquid crystals in a planar geometry. The Landau--de Gennes equation coupled…
Simplified TPLS as a learning tool for high-performance computational fluid dynamics
James Fannon, Jean-Christophe Loiseau, Prashant Valluri +2
We introduce a modified and simplified version of the pre-existing fully parallelized three-dimensional Navier--Stokes flow solver known as TPLS. We demonstrate how the simplified…
Linear and nonlinear instability in vertical counter-current laminar gas-liquid flows
Patrick Schmidt, Lennon Ó'Náraigh, Mathieu Lucquiaud +1
We consider the genesis and dynamics of interfacial instability in gas-liquid flows, using as a model the two-dimensional channel flow of a thin falling film sheared by counter-cur…
Transient growth calculations obtained directly from the Orr-Sommerfeld matrices
Lennon O'Naraigh
We introduce and validate an algorithm to compute transient amplication factors for the Orr-Sommerfeld-Squire linear theory for parallel two-phase flow. We further introduce direct…
