The three-dimensional turbulent flow in a supercritical pump with complex double-cases based on the integral model combined with the pass-by pipes is computed and simulated by means of a parallel computer and the software FLUENT using the mathematical models (Navier-Stokes equations, RNG k-ε turbulence model and boundary conditions) in Computational Fluid Dynamics (CFD), which aims at improving the...
The three-dimensional turbulent flow in a supercritical pump with complex double-cases based on the integral model combined with the pass-by pressure-balancing pipes is computed and simulated by means of a parallel computer and the software FLUENT using the mathematical models (Navier-Stokes equations, turbulence model and boundary conditions) in Computational Fluid Dynamics (CFD). The effects of...
Based on the maximal velocity distribution uniformity, the minimal velocity-weighed average bias angle of the outlet section and the minimal hydraulic loss of the suction chamber, three optimum object functions of suction chambers of pipeline pumps are established. According to uniform design, ten optimum schemes are determined with the height H3 and the length L as the optimum parameters, and internal...
