The new "spectral-dynamic viscosity model", that allows to account for non-developed turbulence in the subgrid-scales, is discussed. Pseudo-spectral methods, combined with sixth-order compact finite ...

Bay Area startup Boundary Layer Technologies (BLT) has been taking pre-orders for its all-electric, jet ski-like hydrofoil it calls Valo. Despite still being in the prototype phase, the demand for ...

The developed boundary layer forms a gravitationally unstable mixing zone with several orders of magnitude viscosity variation leading to RT instabilities due to the density and viscosity differences.

WASHINGTON — The Biden administration on Thursday said it will establish a 20-year moratorium on mining upstream from Minnesota’s Boundary Waters Canoe Area Wilderness, a vast preserve of ...

Snake-like robots can move not only on dry ground but also in various environments such as water, mud, and clay due to its undulating motion. When a snake-like robot moving in such an environment is ...
