底部スリットを有する開水路流れの特性について(第2報)

Abstract

The flow over bottom racks is investigated theoretically and experimentally. At thefirst, the distribution of velocity, pressure and stream lines in local phenomena whichappear on the drop are analyzed by means of the curved coordinate system and on theassumption of equi-energy along stream line.On the basis of that result, hydraulic characteristics of flow on the bottom racks suchas variation of energy, flow rate or depth of flow are made clear. At the last, characteri-stics of critical point of one-dimensional analysis is examined and water surface profileof the flow over bottom racks or free overfall is explained clearly.
