Simulation of wind turbine wake interaction using the vorticity transport model [PDF]
, 2010 The aerodynamic interactions that can occur within a wind farm can result in the constituent turbines generating a lower power output than would be possible if each of the turbines were operated in isolation.

Quality Assurance Testing for Screening Defective Aluminum Die-cast Rotors of Squirrel Cage Induction Machines [PDF]
, 2018 The recent trend in squirrel cage induction motor manufacturing is to replace fabricated copper rotors with aluminum die-cast rotors to reduce manufacturing cost to stay competitive in the global market. Porosity in aluminum die-cast squirrel cage rotors

Orienting coupled quantum rotors by ultrashort laser pulses [PDF]
, 2004 We point out that the non-adiabatic orientation of quantum rotors, produced by ultrashort laser pulses, is remarkably enhanced by introducing dipolar interaction between the rotors.

Performance and wake analysis of rotors in axial flight using computational fluid dynamics [PDF]
, 2017 Flow field around rotors in axial flight is known to be complex especially in steep descent where the rotor is operating inside its own wake. It is often reported that, in this flight condition, the rotor is susceptible to severe wake interactions ...

A Techno-Economic Analysis of a Cargo Ship Using Flettner Rotors
Journal of Marine Science and Engineering, 2023 In the last twenty years, the global shipping transport demand has strongly increased (around 4% per year since the 1990s), together with the request for new green propulsion technologies to break down carbon emissions and face the costs deriving from ...
