Fluid Dynamics Measurements and Numerical Simulations Around a Circular Cylinder Impinged by a Submerged Slot Jet of Air

Abstract

Submerged slot jets of air, impinging onto a cylinder, have been investigated with a new wind tunnel, which realizes low turbulence intensities at the slot exit. The hot anemometry has been used to measure velocity and turbulence across the section of the jet, at several distances from the slot exit, up to the impinged cylinder. The cylinder has been set at two distances from the slot exit, equal to 4 and 6 times the slot height. The Reynolds number of the jet is equal to 23,300, based on the hydraulic diameter of the slot.
