Fast aerodynamic model for rotor sails in wind-assisted ship propulsion
The maritime industry is increasingly adopting innovative technologies to reduce greenhouse gas emissions and improve the energy efficiency of commercial vessels. Among the most promising solutions is Wind-Assisted Ship Propulsion (WASP), with Flettner rotors (rotor sails) emerging as one of the leading technologies for harnessing wind energy to support ship propulsion. Rotor sails generate aerodynamic…

Wind Tunnel Testing of Iced Conductor Bundles for Galloping Assessment
Background and Motivation Galloping is a large-amplitude, low-frequency aeroelastic instability that may develop on overhead transmission lines under specific combinations of wind conditions and ice accretion. Accurate prediction of galloping requires reliable aerodynamic data, including force coefficients and flutter derivatives, which strongly depend on the geometry of the ice accretion and the conductor bundle configuration.…

Evaluation of athlete effort during competitive bike activities
In the wind gallery of Politecnico di Milano, competitive athletes perform aerodynamic evaluations to improve their performances. The goal is to define the better position and/or equipment to be as competitive as possible from an aerodynamic point of view. Nothing is ever said, however, about the possible differences in terms of the effort of the…
