The dynamic stall is a common phenomenon in horizontal and vertical axis wind, reducing
system efficiency. In order to enhance the aerodynamic performance (L/D) of a NACA0012 …

Dynamic stall has been a technical challenge and a fluid dynamical subject of interest for
more than fifty years; but in the last decade significant advances have been made in the …

This paper presents a two-dimensional implementation of the high-order penalized vortex in
cell method applied to solve the flow past an airfoil with a vortex trapping cavity operating …

Backward-facing steps are commonly formed on wings and blades due to misalignment
between segments or the addition of protective films. A backward-facing step (BFS) is known …

In the present work, airflow over blade section of helicopter rotor in forward flight is
investigated numerically to offer a proposal for reduction or alleviation of dynamic stall on …

Airfoils are mostly inefficient in their off-design conditions. In order to improve the
aerodynamic performance of airfoils in these conditions, using an optimized cavity on airfoils …

This paper describes a combined experimental and computational effort to characterize the
cycle-to-cycle variations previously observed in oscillating airfoil experiments. It is common …
