Is there turbulence in space
WitrynaIf we assume that there is a constant random stirring at the scale L 0, then this input energy cascades down to L ν where it is dissipated. The turbulent cascade is thus char-acterized by an energy input rate per gram of gas ε in units of erg gram −1 sec 1 which in this stationary state is the same as the energy dissipation rate. In k-space ... Witryna1 sie 2011 · The Free Space Optics link with atmospheric turbulences was created in software OptiSystem. The results given by software are compared with Andrews's …
