This paper interprets the stabilized finite element method via residual minimization as a
variational multiscale method. We approximate the solution to the partial differential …

The aerodynamic performance analysis of hybrid air vehicles is quite difficult because its
large Reynolds number but low speed. A combination of the variational multiscale method …

Large eddy simulation (LES) of bluff body flows is performed using a finite element based
formulation which employs a combined subgrid-scale model. The combined model uses the …

An alternative to traditional upscaling of single-rotor turbines for higher power production is
the use of multiple rotors mounted on the same tower. Such multi-rotor configurations have …

The flight responses of quadcopters of various scales (50-1200 lb) are evaluated in the
presence of a 20 kt turbulent headwind. Nominal flight controllers are tuned for each aircraft …

In this article, we illustrate the potential of aerodynamic modifications of road signs to reduce
wind-induced vibrations. Using a real-world sign structure operated by the Minnesota …

This paper presents a variational multiscale (VMS) based finite element method where the
stabilization parameter is computed dynamically. The current dynamic procedure takes in a …

In this work we introduce a well-posed mathematical model for the processes involved in the
artificial circulation of water, in order to avoid eutrophication phenomena, for instance, in a …

Overall a similar trend is observed in the lift force among all cases. The peak normalized lift
is about 9% lower for the highest Reynolds number case as compared to the lower …
