Abstract The influence of the axial mount position of the guide vane on the pressure fluctuation in a nuclear pump (AP1000) is investigated. The characteristics of
the three-dimensional flow inside the nuclear pump are analyzed by means of
numerical simulation. Results indicate that when the axial relative distance
between the guide vane and the pumping chamber is reduced, in conditions of
“small flow,” the efficiency of the pump increases, the pressure inside the pumping chamber decreases, while the losses related to the guide vane grow. Under
large flow conditions, as the efficiency of the pump decreases, More >
