Effect of wind turbulence on wave generation over a viscous liquid
Romain Mathis, Sébastien Cazin, Jeanne Methel +4
When wind blows over the surface of a viscous liquid, a clear transition from irregular small-amplitude streamwise-oriented wrinkles to well-defined nearly two-dimensional regular…
Wake instability past a sphere settling in a strongly stratified flow
Chang-Fan Mo, Matthieu J. Mercier, Jacques Magnaudet +1
The wake of a body moving across the isopycnals of a strongly stratified fluid is characterized by the presence of an intense jet which, under certain circumstances, may become uns…
Deformation and stability of a gas bubble in a biaxial straining flow
Aliénor Rivière, David Fabre, Jacques Magnaudet +1
Taking advantage of the recently developed L-ALE framework [Sierra-Ausin \textit{et al.}, Phys. Rev. Fluids {\bf{7}}, 113603 (2022)], we characterize the linear dynamics of an inco…
A sharp and conservative method for modeling interfacial flows with insoluble surfactants in the framework of a geometric volume-of-fluid approach
Zhong-Han Xue, Jacques Magnaudet, Jie Zhang
Insoluble surfactants adsorbed at liquid-liquid or gas-liquid interfaces alter interfacial tension, leading to variations in the normal stress jump and generating tangential Marang…
Rational constitutive law for the viscous stress tensor in incompressible two-phase flows: Derivation and tests against a 3D benchmark experiment
Jacques Magnaudet, Hadrien Bruhier, Samuel Mer +1
We analyze the representation of viscous stresses in the one-fluid formulation of the two-phase Navier-Stokes equations, the model on which all computational approaches making use…
Lateral migration and bouncing of a deformable bubble rising near a vertical wall. Part 2. Highly inertial regimes
Pengyu Shi, Jie Zhang, Jacques Magnaudet
The fate of deformable buoyancy-driven bubbles rising near a vertical wall under highly inertial conditions is investigated numerically. In the absence of path instability, simulat…
