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

Simulations of :
	Galactic spiral shock waves,
	Binary gas accretion onto blackhole
	Bondi accretion on stars and black holes.
	Spiral Patterns in typhoons/huricanes
