Abstract
Instabilities in flow dynamics play a crucial role in understanding and predicting the behavior of fluids in various practical applications. Vortical structures are fundamental to the growth and saturation of these instabilities, making their study of paramount importance. In this regard, understanding the flow instabilities and the formation of vortical structures is of particular interest in the analysis of the flow dynamics. This research aims to study physical mechanisms responsible for the emergence of three-dimensional instability regimes in flow over cylinders, three-element high lift and National Advisory Committee for Aeronautics ``NACA'' airfoils. The study carries out three-dimensional numerical simulations to analyze the wake flow instabilities and the associated vortical structures. The obtained results can contribute to the development of more accurate predictive models for the behavior and the impact of fluid flows over different engineering systems.
