What are The Basic Flow Ripple Principles?
Flow ripple is created when there is a change in the volume on the outlet side of the gear due to the meshing process. It is generally around 25% to 35% of the mean flow rate in the case of a seven-piston pump, where flow ripple is more significant. To illustrate, the flow ripple resembles a half-sine wave or two humps in the case of a two ...

Flow ripple reduction of an axial piston pump by a
This paper investigates the potential of flow ripple reduction of an axial piston pump by a combination of cross-angle and pressure relief grooves. A dynamic model is developed to analyze the pumping dynamics of the pump and validated by experimental results. The effects of cross-angle on the flow ripples in the outlet and inlet ports, and the piston …

Theoretical and Simulation Investigations on Flow Ripple …
Abstract. The output flow ripple of the axial piston pump is one of the excitation sources for the hydraulic system vibration. The amplitudes of its specific harmonics must be reduced to avoid the resonance with the hydraulic pipeline. In this paper, a method on the nonuniform distribution of the pistons is put forward to adjust the flow ripple. The deflection angles …

High‐Resolution Large Eddy Simulations of Vortex Dynamics Over Ripple
After the merging of ripple 2 and ripple 3 into ripple 2 (Figure 12e), the maximum shear stress decreases gradually from ripple 1 to ripple 4 during the positive flow. The maximum shear stress appears around the maximum free stream velocity over ripple 1 when the flow direction is positive, while over ripple 4 for the negative flow direction.
