Design and Fluid Dynamics Features of a Low-Flow High-Head Pump with Barske-Type Impeller

The article presents the results of research devoted to design and numerical calculation a low-flow high-head centrifugal pump with Barske-type impeller using computer simulation methods. main features fluid flow hydrodynamics, as well influence number geometry on energy cavitation characteristics pump, are found. focus is analysis end gap between blades casing, qualities pump. issue different inlet area investigated. In addition, comparison outlet types selection best option provided. Analysis importance installing ribs in suction line, taking into account vortex structure impeller, was carried out. changes when pumping working high kinematic viscosity given.
