Normally, younger rocks are deposited above older ones, forming predictable geologic layers. In the North Sea, this process ...

When it comes to engines, everyone is always looking for more. More horsepower, more torque, more efficiency. One company has ...

The present work shows how thick boundary layers can be produced in a short wind tunnel with a view to simulate atmospheric flows. Several types of thickening devices are analysed. The experimental ...

Particle image velocimetry (PIV), as a common technology for analyzing the global flow motion from images, plays a significant role in experimental fluid mechanics. In this article, we investigate the ...

ABSTRACT: Boundary layers over concave surfaces may become unstable due to centrifugal instability that manifests itself as stationary streamwise counter rotating vortices. The centrifugal instability ...

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 ...

Boundary layer Whenever a shape is immersed in a fluid, there is a thin layer surrounding it called a boundary layer. It divides the flow and the air slows down near the object’s surface.
