摘要
Abstract
Based on the SST k-ω turbulence model,the numerical simulation of energy loss visualization of pipeline centrifugal pump is carried out by using Reynolds time-averaged method.The calculation results show that the high pressure in the impeller is mainly distributed at the blade outlet,and the pressure in the volute is mainly distributed at the tongue and outlet channel.The pulsation entropy generation is dominant in the energy dissipation of the pipeline centrifugal pump.The energy dissipation of the pipeline centrifugal pump is the lowest under the design condition.The energy dissipation of the small flow condition is 3.4 times that of the design condition,and the energy dissipation of the large flow condition is 2.9 times that of the design condition.The energy dissipation at the inlet edge,pressure surface,outlet edge and tip of the impeller is the largest,and the energy dissipation in the volute tongue and outlet channel is the largest.The research results provide a reference for the low energy consumption design of similar water pumps.关键词
