  • Publication number: 20240208718
    Abstract: A drainage device, a water tank, a ventilation area design method thereof, and a storage medium and an electronic apparatus, wherein the top of the water tank is provided with a ventilation slit, an area of which is adjustable in real time, and the bottom of the water tank is provided with a drainage orifice. A determination model for determining whether bubbles are generated during a drainage process of the water tank is established, and a relationship between an area of the drainage orifice and that of the ventilation slit, which satisfies the condition of no bubble generation during the drainage process, is established on this basis.

  • Patent number: 11781942
    Abstract: A method for determining flow velocity distribution in the roughness sublayer is provided, which uses the experimental device that includes a variable-slope circulating flume system and a flow-measuring system, the variable-slope circulating flume system is used to study flow in the roughness sublayer, and the flow-measuring system is used to measure flow velocity in each zone in the flume. In the variable-slope circulating flume, the method according to the invention uses cylindrical aluminum rods to simulate large-scale roughness elements, and the submergence, the average bulk flow velocity and the distribution density of roughness elements are changed.
