THE EFFECT OF BODY GEOMETRY AND INCIDENT FLOW CHARACTERISTICS ON THE DISTORTION OF TURBULENCE

An experimental study of the characteristics of a turbulent field upstream from a cylinder normal to the mean flow is presented for various geometries of the cylinder section. Four configurations were tested: a flat plate of 0.05 x 0.01m section, a square bar of 0.05 x 0.05m, a rectangular bar of 0.05 x 0.1m and a circular cylinder, 0.05m diameter. Tests were carried out for grid and shear incident flows to study the effects of the turbulence characteristics of the incoming flow. A method to deduce the pressure spectrum at the stagnation point by extrapolating the longitudinal velocity spectra measured along the stagnation streamline was used. Theoretical analysis was done to establish formulae to approximate both velocity and pressure spectra.
