概要

• 論文の詳細を見る

• Equations of motion of solid particles in a pump impeller having low specific speed were solved numerically with assumptions of an inviscid and incompressible quasi-three dimensional flow, and the general behavior of solid particles in the pump was clarified. The particle trajectories and forces acting on particles, the diameters of which range from 0.1 to 0.5 mm and the specific-gravities from 1.8 to 5.4 were obtained for different flow capacities. The locations and the velocities, with which the particles impinge on the boundary surface of the pump, were also discussed in order to predict the erosion damage in pumps.
