Fuel consumption and greenhouse gas emissions are huge priorities in the aviation industry – passenger airliners chew through amazing quantities of fuel. Take the Boeing 747, which guzzles somewhere ...

The dynamics of rotor wakes and the behaviour of tip vortices have emerged as critical areas of investigation in rotorcraft aerodynamics. These phenomena underpin not only the performance and ...

This paper describes a series of ongoing experiments to capture the details of perpendicular vortex-airfoil interaction. Three test cases explored are: 1) a 21% thick symmetric airfoil at 1.1° angle ...

This paper describes the formulation of a new model for the wake of a horizontal-axis wind turbine. As in many other models, the trailing vorticity is represented by a number of vortex lines which ...
