Abstract
Wind tunnels are useful tools when we investigate the aerodynamics characteristics of scaled models of (i) runners of track-and-field athletics and marathon, (ii) land vehicles such as trains and cars and (iii) creatures like flying fishes. In wind-tunnel experiments which are the most effective approaches to such studies, a moving-belt system is indispensable for precise aerodynamic measurements considering the ground effect. In the present study, we develop a moving-belt system for fundamental and accurate wind-tunnel experiments concerning the ground effect, and show its basic performance such as the profiles of time-mean flow velocity and turbulence intensity above the moving belt of the system using a hot-wire anemometer. And in order to show the effectivity of the moving-belt system, we put in the thin flat plate above the moving-belt and run visualization and flow analysis to find out ground effect by using moving-belt.
