Disruption of SSP/VWI states by a stable stratification
(Cambridge University PressJournal of Fluid Mechanics, 2015-11-06)
We identify ‘minimal seeds’ for turbulence, i.e. initial conditions of the smallest possible total perturbation energy density Ec that trigger turbulence from the laminar state, in stratified plane Couette flow, the flow ...
Dependence on aspect ratio of symmetry breaking for oscillating foils: implications for flapping flight
(Cambridge University PressJournal of Fluid Mechanics, 2015-12-07)
Using two-dimensional direct numerical simulations, we investigate the flow in a fluid of kinematic viscosity ν and density ρ around elliptical foils of density ρ_s with major axis c and minor axis b for three different ...
