| Research Abstract |
By individually controlling each fan, an active type wind tunnel, a multiple-fan wind tunnel, is developed to successfully simulate non-stationary wind flows due to wind speed and direction changes. A procedure to investigate non-stationary effects on surface pressures on prism cylinder models immersed in such wind flow is established. Further, in order to reproduce the extremely non-stationary phenomenon induced by tornado-like wind flow based on tornado/downburst database of Japan Meteorology Agency is applied to form several typical patterns for the examination of non-stationary effects on prism cylinder models.
