Abstract

Many studies on flying of a piece of wind-borne debris are based on the assumption that its mass distribution is non-eccentric. This report focused on the mass eccentricity of plate-like debris, and the effects of the eccentricity on the distance, angle and speed of flying were investigated using a wind tunnel test and a numerical calculation. The numerical results corresponded well to the experimental results. By parametric studies on the eccentricity and initial angle of plate, it was found the eccentricity of plates had a strong impact to its flying distance under strong winds. Especially, the flying distances of plates with eccentricity of 8% to 18% are much bigger than those of non-eccentricity plates.
