The characteristics of this wind-tunnel which can generate arbitrary pattern of wind velocity varying with time were described firstly. The representative airflow patterns are four in a steady-velocity wind, a pulsating-velocity wind, a gust of wind, and stepwise changing wind. A preliminary experiment was made of the steady wind in three types of vehicle model and theaerodynamic forces acting on the models were compared. Subsequently, a fundamental experiment was conducted of an Ahmed's vehicle model under a pulsating airflow condition and a discussion was given for the unsteady aerodynamic forces. These results suggested that the windtunnel is very useful to investigate the unsteady aerodynamics for road vehicles., application/pdf}, title = {〈技術報告〉近畿大学次世代基盤技術研究所可変風速型風洞実験装置について}, year = {2012}, yomi = {スミダ, マサル and モリタ, セイヤ} }
