Description

Transient drag forces acting on a square prism with several angles of attack<br>in quickly change of wind speed like a step function were measured <br>experimentally by towing tank equipment. As results of this study, it was <br>clarified that an aerodynamic transient drag force was consistent as a summation <br>of three kinds of forces; a dynamic pressure force, an inertia force controlled<br>by a non-dimensional acceleration ratio, and a force produced by forming <br>the flow field around the prism. Moreover, it was indicated that the behaviors <br>of these forces were almost the same in the different initial conditions, such as<br>a quiescent state and blowing wind states.<br>
