Optical diagnostics of complementary vortical rings induced in air by an impulse of pressure on a hole
Hilbert–visualization of phase disturbances in light fields is discussed. Evolution of the complementary vortex rings induced in the air by an impulse of pressure on an aperture in a wall of the chamber is experimentally investigated. Numerical modelling structure of the vortical rings is executed.
