A Numerical Study of Correlation between Recirculation Length and Shedding Frequency in Vortex Shedding Phenomena
Authors: , ,
Abstract: The purpose of this paper is to characterize and to estimate the recirculating length behind an
aerodynamic profile in ground effect with Gurney Flap. The flow characterization at high Reynolds numbers
was performed by means of numerical analysis. A correlation between the size of the recirculation length and
the frequency of vortex shedding was studied. The vortex shedding has a characteristic frequency, which, in
this work, is correlated to the size of a recirculation length defined by the authors. The numerical investigation
methodology applied to the profile with Gurney Flap, was previously developed on the well-documented test
case of the flow around a cylinder at high Reynolds. The case was chosen to investigate and to validate the
numerical approach with experimental data.
