Abstract In order to grasp the reverse startup characteristics of a small radial vane pump in the case of misoperation, a circulation piping system that includes
the pump is established. Numerical simulation of the full three-dimensional unsteady incompressible viscous flow is performed based on the slip-grid
technique and user-defined functions (UDF). According to the results, the static pressure fluctuation is small at the inlet of the centrifugal pump
during the reverse startup, which differs significantly from the forward startup. Compared to the impeller rotational speed, the time required for the
shaft power, head and flow curves to reach stability is lagged,… More >
