Abstract
The invention relates to a device which determines aerodynamic characteristics of a wall. The device comprises a drum secured to a shaft, an enclosure defining with the drum at least one test zone (,), a test fluid delivery line communicating with this test zone and means which determines a parameter representative of the friction factor of the fluid in the at least one test zone. The at least one test zone has a determined width 1 or gap width, for a given rotating speed of the drum and a test fluid having known characteristics (visosity, density . . . ), so that the fluid has a turbulent flow in the vicinity of the wall(s) to be tested, the turbulent flow corresponding to a given Reynolds value Re.
