Magnetic tornado is stirring up the haze at Jupiter's poles     Magnetic tornado  Magnetically  Hydrocarbon       font style='font-size:12px;'> 2024/12/11
Dark ovals in Jupiter's polar haze, visible only at UV wavelengths, were first noticed 25 years ago, then ignored. A new study shows that these dark UV ovals are common, appearing at the south pole in...
From Stirring to Mixing in a Stratified Ocean     Stirring  Mixing  Stratified Ocean       font style='font-size:12px;'> 2015/8/3
Over fifty years ago, Carl Eckart described the sequence of processes as a passive scalar is stirred and mixed in a turbulent flow (Eckart, 1948). At first, during the stirring phase, the variance of ...
While pursuing the goal of turning a cloud of ultracold atoms into a completely new kind of circuit element, physicists have demonstrated that such a cloud-known as a Bose-Einstein condensate (BEC)-ca...
Most of dwarf spheroidal galaxies in the Local Group were probably formed via environmental processes like the tidal interaction with the Milky Way.We study this process via N-body simulations of dwar...
We address the challenge of optimal incompressible stirring to mix an initially inhomogeneous distribution of passive tracers. As a quantitative measure of mixing we adopt the H􀀀1 norm of th...
Topological optimisation of rod-stirring devices     Topological optimisation  rod-stirring devices       font style='font-size:12px;'> 2010/4/6
There are many industrial situations where rods are used to stir a fluid, or where rods repeatedly stretch a material such as bread dough or taffy. The goal in these applications is to stretch either ...
Abstract: Minerals in surface environments form in both turbulent and non-turbulent systems. This study compares the properties of Al goethite formed from ferrihydrite at 60 °C in 0.3 M KOH with and w...
