A new set-up is proposed to numerically investigate turbulent multi-material mixing in the presence and in the absence of a gravitational field. The set-up consists of an initial unperturbed interface that separates two fluids in an existing isotropic velocity field. The initial unperturbed interface evolves into a turbulent multi-material mixing region due to the fluctuating velocity field. Fo...

In this study we investigated the effect of gravity on multi-digit prehension to know how the digits’ force and moment are organized in the imposed static constraints according to the gravity. Specifically, we tested if decoupling of grasping and rotational equilibrium control is even valid during grasping in the microgravity condition. There were two experimental conditions: gravity-induced (G...

We study high-amplitude folding in layered rocks with two-dimensional numerical simulations. We employ the finite-element method to model shortening of an incompressible multi-layer with power-law viscous rheology. The Lagrangian numerical mesh is deformed and re-meshed to accurately follow the layer interfaces. Three settings are considered: (i) pure shearing of a confined multi-layer, (ii) si...
