Annotation	The swirling jet breakdown unsteady process has been examined experimentally using stereo PIV time resolved method. The experimental setup has been designed, build and prepared in HFI. It generates helical swirling jet and allows implementation of the jet breakdown. The Bi-Orthogonal Decomposition (BOD) method has been chosen for the data analysis the Proper Orthogonal Decomposition applied both in space and time. the BOD method offers decomposition into energetic modes in space (toposes) and in time (chronoses).
