Abstract

The means of prediction of the unsteady aerodynamic effects associated with gust of wind are rare and difficult to develop. This paper proposes a state of the art on the experimental and numerical techniques intended to improve comprehension of the physical phenomena and to quantify the effects of the gust of the wind. For each solution, the experimental and/or modelisation conditions are recalled and the principal results presented.
