The flow in a spherical cavity on a curved round pipe is a canonical flow that describes well the flow inside a sidewall aneurysm on an intracranial artery. Intracranial aneurysms are often treated with a flow-diverting stent (FDS), a low-porosity me

International audience; In this contribution the effects of a nearly axisymmetric standing acoustic wave on the transport properties of a multi-phase jet are examined. The standing wave is seen to drive liquid droplets from the pressure anti-node , w

When a high-speed gas flow destabilizes a liquid jet into a spray (atomization), the gas-liquid interface undergoes instabilities that play a key role in the breakup events. We use high-speed backlit imaging to track the maxima of such interfacial pe

International audience; We investigate the behavior of large particles in a transitional swirling flow in a closed vessel, focusing on both their transport and flow sampling. We conduct a Lagrangian study of slightly buoyant particles, considering th

Flow in side-wall cerebral aneurysms can be ideally modelled as the combination of flow over a spherical cavity and flow in a curved circular pipe, two canonical flows. Flow in a curved pipe is known to depend on the Dean number De, combining the eff
