The main purpose of the project is the study of the turbulent flow in high Reynolds number (Re) regime, not accessible in today’s laboratories. Accretion systems are unique cosmic experiments to do so. The turbulence minimum dimension scales in the fluid are described by the Re. The largest scales of fluid motion are set by the overall geometry of the flow and are dissipating into smaller eddies up to the minimal dimension scale. From the basic fluid mechanics it is well known that higher Re numbers yield smaller minimal dimension scale. From Re about 10^6 the dissipation toward smaller scales of turbulent elements is so strong that the fluid becomes quasilaminar. The bigger eddies should dissipate and hence disappear. Today Re estimates from Earth goes toward a value of about 10^8. What is happening then? The typical Re in an accretion disk of cataclysmic variables is of about 10^12 and one of the possibility to explain flickering are turbulence in the disc. Can the flow tell something about the size of the turbulence? Why do we observe the flickering if the turbulence should "disappear" for Re ~ 10^6?
