LEC - Laboratory Experiments of Cosmic Hydrodynamics- 
 
Laboratory experiments of cosmic hydrodynamics for simulating
higher-order waves and shocks using laboratory hydraulic jumps
on the rotating fluid. 

Simulations of : 

Galactic spiral shock waves,
Binary gas accretion onto blackhole
Bondi accretion on stars and black holes.
