The angle between a suitable reference line in a body (such as the axis of a body of revolution or the chord line of a wing) and the projection of the velocity relative to the ambient undisturbed relative airflow air on to the plane of symmetry.  3, record 1, English, - angle%20of%20attack

Record number: 1, Textual support number: 1 CONT

The angle at which the airfoil meets the relative airflow is called the angle of attack. As the angle of attack is increased, the changes in pressure over the upper and lower surfaces and the amount of downwash(i. e. air deflected downward) increase up to a point(the stalling angle). Beyond this angle, they decrease.  4, record 1, English, - angle%20of%20attack

L'angle auquel le profil aérodynamique rencontre l'écoulement d'air relatif s'appelle l'angle d'attaque. Quand on augmente l'angle d'attaque, les variations de pression (au-dessus et en dessous de l'aile), de même que la quantité d'air repoussé vers le bas augmentent et cela, jusqu'à un certain point (angle de décrochage). Au-delà de cet angle, elles diminuent.  3, record 1, French, - angle%20d%27attaque

At the request of member utilities, EPRI is managing a multi-year collaborative applied research effort focused on developing improved plume rise and downwash sub-models for incorporation into regulatory air quality dispersion models.... A field measurements program was performed from February 10-March 5, 1994 to characterize plume rise and building-induced downwash at a representative combustion turbine facility, under a variety of meteorological conditions.... PRIME [Plume Rise Model Enhancements] explicitly calculates the local slope of the mean streamlines as a function of building shape and wind angle, and coupled with a numberical plume rise model, determines the change in plume centerline location with downwind distance.  4, record 3, English, - plume%20rise
