- GENERATION OF TIDAL RESIDUAL CURRENT USING THE BOTTOM ROUGHNESS TO BEND FLOW DIRECTION
抄録
Nowadays in most of semi-enclosed bays water qualities have been deteriorated. Wehave proposed the method to create and control the tidal residual current by bottom roughnessfor activating the tidal exchange. In this paper we introduced the new type of bottomroughness with a function to bend the flow direction and experimentally developed the mosteffective shape. Next we tried to examine the effect of the bending roughness by numericasimulation in the model bay. As a result, it is made clear that quarters of the cylinder arrangedin two rows can get the large drag force in the normal direction of the flow and thatthe tidal exchange is promoted by the combination of the bottom roughness and the bending roughness.
