Could the phenomenon of vortex bursting be exploited to reduce wake turbulence? Well, it's the only way to get rid of the Turbelence. Turbulence is caused by vortexes and they obviously must burst, before they completely stop. My question is, what are the physical variables which promote or inhibit vortex bursting and, if they can be controlled, can this ...

Yes, "We" have. The reason why Energy blows up as the scale goes down, ist the fact that there is Surfaces in the fluid. "Turbulence" ist fluid broken in parts. If you have one big size eddy, it doesn't have much of a surface. But if you have a many small ones, they have exponentially more surface. And Surface is Energy! Every m2 of Watersurface has 72.8 ...

If you would just calculate the Reynold number to Troposphere, say, 10 000 m thick. Kinematik viscosity of air is, say, 1.2 x10^-5 so you found that with Re 4000 you would have just need to have a 0.0000048 m/s velocity In praxis, though, this is not the case, but it's a stratified fluid system; ...

YES. It can "Laminarize" the flow. And this will reduce the friction too. If I think adding infinite number of infinitely thin dividers, we are then actually reinforcing the fluid like concrete is reinforced with steel. In praxis we are actually just changing the viscosity of the fluid, which -obviously- makes it less turbulent. Study hydraulic ...

One of the first complete study was performed by Obukhov in 1949 with his famous paper The structure of the temperature field in a turbulent flow. You can find it here [link] (This is a PDF file, you can check by searching the report title on Google). It is a nice thing to know. A complete review was written by Warhaft in the Annual Review of Fluid ...
