Record number: 2, Textual support number: 1 CONT

Success of vortex theories in the performance analysis of horizontal axis wind turbines depends greatly upon accurate specification of the geometry of the vortex wake... An earlier wake model of helicopter rotors is extended for wind turbine applications, the fast free wake method(FFW). The FFW was accomplished by partitioning the flow field downstream of the rotor into three regions :(1) the near wake, modeled as a series of straight vortex lines;(2) the intermediate wake, modeled as a number of vortex rings; and(3) the far wake, taken to be a semi-infinite cylindrical wake.  3, record 2, English, - fast%20free%20wake%20method

Numerical modelling focused on the continued development of a prescribed wake vortex model for HAWT [horizontal axis wind turbine] performance prediction. This model represents the turbine blades as lifting lines from which emanate filaments of trailed vorticity.

Vortices generally dissipate or break up in one of three ways : first, over a long period of time, turbulent diffusion can enlarge each wake so that the wakes merge and dissipate; second, disturbances along the length of the vortices become unstable and sinuous oscillations develop which cause the vortices to touch and link together; and third, a sudden structural change known as vortex breakdown or bursting can abruptly widen the vortex care.  1, record 10, English, - vortex%20breakdown

Les tourbillons se dissipent ou se désintègrent généralement selon l'un des trois modes ci-après. Dans le premier mode, une longue période de diffusion turbulente peut dilater chacun des sillages au point qu'ils se mêlent et se dissipent. Dans le deuxième mode, des perturbations qui se produisent le long des tourbillons deviennent instables et la formation d'oscillations sinueuses amène les tourbillons à se rejoindre et à se lier. Dans le troisième, une modification subite de structure, appelée dislocation ou éclatement des tourbillons, peut faire brusquement gonfler leur noyau.  1, record 10, French, - dislocation%20des%20tourbillons
