The paper presents a Fluid Structure Interaction (FSI) method for hydroelastic water entry.
The method assumes that the momentum exchange between the fluid and solid body can be …

This study presents the spreading of a single filament of a yield stress (viscoplastic) fluid
extruded onto a pre-wetted solid surface. The filaments spread laterally under surface …

The spreading under surface tension and gravity of a droplet of yield-stress fluid over a thin
film of the same material is studied. The droplet converges to a final equilibrium shape once …

We study the injection flow of a heavy viscoplastic fluid into a light Newtonian fluid, via
modelling and experiments. The injection is carried out downward, via an eccentric inner …

Extensibility is beyond the paradigm of classical soft glassy materials, and more broadly,
yield-stress fluids. Recently, model yield-stress fluids with significant extensibility have been …

The impact of fluid drops on solid substrates is a cardinal fluid dynamics phenomenon
intrinsically related to many fields. Although these impacting objects are very often non …

We experimentally study the impacts of viscous, immiscible oil drops into a deep pool of
water. Within the target liquid pool, the impacting drop creates a crater, whose dynamics are …

One of the greatest challenges in performing numerical simulations of viscoelastic flow is
how to choose the model parameters in order to be able to achieve quantitative agreement …

We experimentally study miscible displacement flows of a light Newtonian fluid by a heavy
viscoplastic fluid, in a vertical pipe with a large aspect ratio (⁠ δ− 1≫ 1⁠). We use camera …

Non-spherical hydrogel particles are of fundamental interest and can find use in a variety of
applications ranging from pharmaceuticals to biomedical to food. Here, we report a new …
