title = "Finding of parameters of helical symmetry for unsteady vortex flow based on phase-averaged PIV measurement data",
abstract = "The phase-averaged velocity distributions were applied for calculation of parameters of a precessing vortex core; these were the input data for calculation of precession frequency by a formula derived from the helical vortex theory. It was demonstrated that the calculated frequency is within 10% error from the frequency measured in experiments. These results confirm the theory validity, and this opens opportunities for analysis of mechanisms controlling the precessing vortex core and external factors.",
