Here, for non-breaking short surface waves, we have experimentally determined the value of the turbulent eddy viscosity νT or its ratio νT*≡νT/ν, where ν is the water kinematic viscosity. The non-breaking wave-generated turbulent eddy viscosit

Investigation of Turbulent Tidal Flow in a Coral Reef Channel Using Multi-Look WorldView-2 Satellite Imagery

Autor: George Marmorino

Publikováno v: Remote Sensing, Vol 14, Iss 3, p 783 (2022)

The general topic here is the application of high-resolution satellite imagery to the study of ocean phenomena having horizontal length scales of several meters to a few kilometers. The present study investigates whether multiple images acquired quit

Stereo Thermal Marking Velocimetry

Autor: Ivan Savelyev, Julian Fuchs

Publikováno v: Frontiers in Mechanical Engineering, Vol 4 (2018)

This paper presents a novel approach to measuring and mapping shape and motion of the water surface. The approach combines and borrows from existing techniques, such as stereo imaging shape recognition and tracking, infrared (IR) laser marking and th

We describe a new field campaign over a steep, snowy $$30^{\circ }$$ alpine slope, designed to investigate three recurrent issues in experimental studies of steep-slope katabatic winds. (1) Entrainment is known to be present in katabatic jets and has
