This is the second of two articles with the main, and largely self-explanatory, title “Rotor
theories by Professor Joukowsky”. This article considers rotors with finite number of blades …

This chapter is divided into two parts, LES and DNS. In the first part, the LES turbulence
model is derived from first principles, and its terms are described in detail. The usage of LES …

A helicopter is subjected to a wide variety of flight conditions with disparate objectives; these
include efficient cruise and hover, and high-performance maneuvering. The hover condition …

Two modal decomposition techniques are employed to analyse the stability of wind turbine
wakes. A numerical study on a single wind turbine wake is carried out focusing on the …

The aim of the present paper is to obtain a better understanding of the stability properties of
wakes generated by wind turbine rotors. To accomplish this, a numerical study on the …

In the present study the wake flow past an isolated propeller operating in oblique flow
conditions is investigated experimentally. In particular, the investigation concerns a …

This report reviews the available literature on the aerodynamics of wind turbines and wind
farms. Firstly, two introductory chapters are devoted to the physics of the flow around a wind …

Numerical simulations using CFD are performed for wind turbine applications. The aim of
the project is to get a better understanding of wake behaviour that cannot be obtained by …

Modal decomposition techniques, flow field, and spectral analysis are employed to
investigate the wake dynamics and destabilization mechanisms of a four-bladed marine …

We investigate the instability of a single helical vortex filament of small pitch with respect to
displacement perturbations whose wavelength is large compared to the vortex core size. We …
