Experimental study and analytical reconstruction of precessing vortex in a tangential swirler

► We report on experimental and analytical study of swirling flow in the near-field of a tangential swirler. ► We found strong recirculation penetrating the nozzle chamber at higher swirl numbers. ► We found extreme r.m.s. of velocity fluctuations in the annular jet due to PVC-induced deterministic...
