Kelvin-Helmholtz TimescaleThe Kelvin-Helmholtz timescale is the time required for a star to radiate its own gravitational energy. It is defined as the ratio of the star's gravitational energy GM2/R (where M and R are the...doi:10.1007/978-3-642-27833-4_5502-1D. Galli...

Each individual billow, resembling a cat's eye, had a horizontal length scale of 200 m, a vertical scale of 100 m, and a timescale of 7 min, near the local buoyancy frequency. Overturns were observed frequently in the billow cores and the upper eyelids. The turbulent kinetic energy ...
Our calculations indicate that Kelvin-Helmholtz modes can operate fast enough to amplify the magnetic field strengths in superwinds within the timescale of the outflow. Plasma-neutral gas simulations show that the non-linear evolution of the Kelvin-Helmholtz modes resemble the pure MHD one and ...
The timescale of the billows is approximate 6 min. By analyzing the changes of potential energy during the mixing process, results show that the existence of K-H instability induces intense vertical mixing, which can greatly increase mixing efficiency in the North Passage of the Yangtze River ...
