Numerical simulation of orbitally shaken viscous fluids with free surface

Alfio Quarteroni, Florian Maria Wurm, David Hacker, Marco Discacciati, Stéphanie Tissot, Samuel Quinodoz

Orbitally shaken bioreactors are an emerging alternative to stirred-tank bioreactors for large-scale mammalian cell culture, but their fluid dynamics is still not well defined. Among the theoretical and practical issues that remain to be resolved, the char ...

Charge transfer and Penning ionization of dopants in or on helium nanodroplets exposed to EUV radiation

Marcel Drabbels, Nils Benedict Brauer, Robert Richter

He nanodroplets are widely used as a cold, weakly interacting matrix for spectroscopy of embedded species. In this work we excite or ionize doped He droplets using synchrotron radiation and study the effect onto the dopant atoms depending on their location ...

Investigation of droplet shedding in flow focusing geometries using the boundary element method.

François Gallaire, Mathias Nagel

Shedding of droplets in a flow focusing junction is standard technique in two-phase microfluidics. This break-up is driven by a capillary instability. Here we present a depth-averaged approach to simulate these complex phenomena. Since the physical mechani ...

Eastern pacific emitted aerosol cloud experiment

Athanasios Nenes, Robin Lewis Modini, Zheng Wang

A coordinated field experiment, the Eastern Pacific Emitted Aerosol Cloud Experiment (E-PEACE) campaign, in which the effects of well-defined aerosol perturbations on marine stratocumulus clouds were probed via in situ aircraft and satellite observations. ...

Phase compositions and equilibria in the CaO-Al2O3-Fe2O3-SO3 system, for assemblages containing ye'elimite and ferrite Ca-2(Al,Fe)O-5

Karen Scrivener

Phase equilibria in the CaO-Al2O3-Fe2O3-SO3 system have been studied, mainly at 1325 degrees C. In particular the solid solution compositions of ye'elimite Ca-4(Al6O12)SO4 and brownmillerite (C-2(A,F)) phases have been analysed and used to estimate the com ...

Quasi-elastic neutron scattering in the multi-GPa range and its application to liquid water

Livia Eleonora Bove Kado

We present a method which allows quasi-elastic neutron scattering (QENS) at multi-GPa pressures, i.e., pressure conditions which are an order of magnitude higher than possible with QENS till now. The technique uses an opposed-anvil geometry with a sample c ...

Droplet number uncertainties associated with CCN: An assessment using observations and a global model adjoint

Athanasios Nenes

We use the Global Modelling Initiative (GMI) chemical transport model with a cloud droplet parameterisation adjoint to quantify the sensitivity of cloud droplet number concentration to uncertainties in predicting CCN concentrations. Published CCN closure u ...

Skating on a Film of Air: Drops Impacting on a Surface

John Martin Kolinski

The commonly accepted description of drops impacting on a surface typically ignores the essential role of the air that is trapped between the impacting drop and the surface. Here we describe a new imaging modality that is sensitive to the behavior right at ...

The Life and Death of the Air Film Beneath an Impacting Drop

John Martin Kolinski

Droplet impact is ubiquitous in our everyday experience; yet many mysteries associated with the phenomenon remain, including the role played by air during the impact process. When a liquid meets a solid surface in an atmosphere, it must drain the air benea ...

Interface-induced recirculation within a stationary microfluidic drop

François Gallaire

We study the flow within a stationary drop in a Hele-Shaw cell. The experiments are performed in a microfluidic channel, whose surface is patterned with a single hole that serves to anchor the drop while the outer fluid continues to flow. The recirculation ...
