Deformation of drops by outer eddies in turbulence
Alberto Vela-Martín, Marc Avila
Drop deformation in fluid flows is investigated here as an exchange between the kinetic energy of the fluid and the surface energy of the drop. We show analytically that this energ…
Non-modal transient growth of disturbances in pulsatile and oscillatory pipe flow
Duo Xu, Baofang Song, Marc Avila
Laminar flows through pipes driven at steady, pulsatile or oscillatory rates undergo a sub-critical transition to turbulence. We carry out an extensive linear non-modal stability a…
Effect of filter kernel on scale-energetics of near-wall turbulent structures
Daniel Feldmann, Mohammad Umair, Marc Avila +1
Inter-scale energy fluxes, , are widely used as a diagnostic tool to analyse energy transfer across length scales, , in turbulence data. Here, we investigate how the choice…
Resonances in pulsatile channel flow with an elastic wall
Duo Xu, Matthias Heil, Thomas Seeböck +1
Interactions between fluids and elastic solids are ubiquitous in application ranging from aeronautical and civil engineering to physiological flows. Here we study the pulsatile flo…
Nonlinear hydrodynamic instability and turbulence in pulsatile flow
Duo Xu, Atul Varshney, Xingyu Ma +4
Pulsating flows through tubular geometries are laminar provided that velocities are moderate. This in particular is also believed to apply to cardiovascular flows where inertial fo…
