1113 水底の形状変化を用いた水滴落下による騒音の緩和
詳細
The splash caused by a falling water droplet is often seen in our life but the noise induced by it sometimes annoys us. In the present paper, the form of splash was observed using high speed camera in order to reduce the noise and compared between the form of splash when a droplet fell into the water tank with flat bottom and that when a droplet fell into the water tank with slope bottom. As the result the column-type splash formed by the droplet on the slope bottom inclined to the upper direction of slope and the noise by splash was disappeared.
