| 内容記述 | A numerical and an experimental investigation on a suction vortices, free vortices and subsurface vortices behavior in the model sump system with multi-intakes is performed at several flow rates and water levels. A test model sump and piping system were designed based on Froude similitude for the prototype of the recommended structure layout by HI-9.8 Standard for Pump Intake Design of the Hydraulic Institute. A numerical analysis of three dimensional multiphase flows through the model sump is performed by using the finite volume method of the CFX code with multi-block structured grid systems. A k-ω Shear Stress Transport turbulence model and the Rayleigh-Plesset type cavitation model are used for solving turbulence cavitating flow. Several types of free surface and submerged vortex which occurs with each different water level are identified through the experimental investigation. Minimum water levels and swirl angles were determined for the first appearance of 6-types of surface vortices. From the numerical analysis, the vortices are reproduced and their formation, growing, shedding and detailed vortex structures are investigated. | |||||
