Results on unsteady vortex breakdown are obained simultaneously using two diagnostics methods: a) determination of velocity fields by particle tracks (Particle Image Velocimeter - PIV), b) determination of velocity fields by Laser Doppler Anemometry (LDA), are presented.The experiments data are in some regimes supplemented by th 3D computations of the incompressible Navier-Stokes equations in cylindrical coordinates. Perfect agreements between calculation and experiment reveal efficiency of both diagnostics method for pulsating vortex breakdown and numerical method for solution to 3D unsteady Navier-Stokes equations.
