Stages of turbulence generation and decay in a T-shaped mixer

The T-shaped mixer is widely used in fundamental studies of chemical engineering. Its transitional regime is well understood, whereas the turbulent dynamics has received scarce attention so far. Here, we perform direct numerical simulations of the turbulent regime for Reynolds nu...

Bubble detachment from circular cavities and flat surfaces

We determine the maximum stable volume of bubbles attached to flat surfaces as a function of the contact radius, contact angle, and capillary length. Using a shooting method to solve...
