Bubble detachment from circular cavities and flat surfaces
Ianto Cannon, Stefan Endres, Lutz Mädler +1
We determine the maximum stable volume of bubbles attached to flat surfaces as a function of contact radius, contact angle, and capillary length. By solving the Young-Laplace equat…
Scaling of the minimal energy for turbulence transition in pipe flow
Patrick Keuchel, Daniel Morón, Marc Avila
Predicting the transition of turbulence in pipe flow remains a fundamental problem in fluid dynamics. We use a variational approach to compute nonlinear optimal perturbations to th…
A causal model of drop breakup in turbulence
Daniel Morón, Ianto Cannon, Alberto Vela-Martín +1
Fragmentation of drops and bubbles in turbulence controls interfacial area generation, mixing, and transport in environmental and engineering flows. Reduced-order models of breakup…
Stages of turbulence generation and decay in a T-shaped mixer
Mohammad Mehdi Zamani Asl, Marc Avila
The T-shaped mixer is widely used in fundamental studies of chemical engineering. Its transitional regime is well understood, whereas the turbulent dynamics has received scarce att…
Experimental study of turbulent mixing in a T-shaped mixer
Huixin Li, Mohammad Mehdi Zamani Asl, Bastian Bäuerlein +3
One of the most widespread canonical devices for fluid mixing is the T-shaped mixer, in which two opposing miscible liquid streams meet at a junction and then mix along a main chan…
Nonlinear optimal perturbation growth in pulsatile pipe flow
Patrick Keuchel, Marc Avila
Pulsatile fluid flows through straight pipes undergo a sudden transition to turbulence that is extremely difficult to predict. The difficulty stems here from the linear Floquet sta…
Bayesian minimisation of energy consumption in turbulent pipe flow via unsteady driving
Felix Kranz, Daniel Morón, Marc Avila
Turbulence accounts for most of the energy losses associated with the pumping of fluids in pipes. Pulsatile drivings can reduce the drag and energy consumption required to supply a…
Probabilistic thresholds of turbulence decay in transitional shear flows
Daniel Morón, Alberto Vela-Martín, Marc Avila
Linearly stable shear flows first transition to turbulence in the form of localised patches. At low Reynolds numbers, these turbulent patches tend to suddenly decay, following a me…
On the nature of laminar-turbulence intermittency in shear flows
Marc Avila, Björn Hof
In pipe, channel and boundary layer flows turbulence first occurs intermittently in space and time: at moderate Reynolds numbers domains of disordered turbulent motion are separate…
Revealing the state space of turbulent pipe flow by symmetry reduction
Ashley P. Willis, Predrag Cvitanovic, Marc Avila
Symmetry reduction by the method of slices is applied to pipe flow in order to quotient the stream-wise translation and azimuthal rotation symmetries of turbulent flow states. With…
