In the present research, our pump model is designed to visualize the jet flow near a notch of a valve plate in an axial piston pump. The cavitation cloud can be observed clearly using a high-speed video camera from the perpendicular direction to the axis and the direction of the jet flow and the area of the cavitation cloud are obtained. A valve plate with V-shaped groove type is used and the regions of the occurrence of the cavitation are analyzed using an image processing technique. Furthermore the computational fluid dynamics is employed using the 2-D vortex method combined with boundary element method to estimate the occurrence and the region of the cavitation cloud.
