Abstract

Background: Pumps with increased noise, vibration and harshness (NVH) requirements are in high demand in various fields of both civil and military equipment, especially underwater, due to stricter standards of sound pollution and the development of vehicle tracking systems. Disc pumps are one of the “quietest” pumps, due to their simple design and the absence of elements that cause eddy formation, but at the same time they ensure less pressure than, for example, vane pumps, which is why the former have not been studied in detail at the moment. Despite this, these machines require optimization, design innovations and deeper analysis in the field of vibrational intensity reduction.

Aim: Study of vibrational intensity of a disc pump using hydrodynamics and solid-state modeling, optimizing the geometry of the flow part to achieve continuous flow.

Methods: The calculation is a combination of computational fluid dynamics and computer-aided design, was performed in the Simcenter STAR-CCM+ software package, the simulation included unsteady conditions, the Detached Eddy Simulation (DES) turbulence model was selected for hydrodynamics, vibrational dampers were modeled. The HEEDS software is used for optimization.

Results: A 3D model of the entire pump, a vibration acceleration spectrogram, and a velocity field in the optimized flow part were obtained.

Conclusion: The practical value of the study lies in the obtained qualitative and quantitative data on the vibrational intensity of disc pumps, as well as in the correct body of mathematics for optimizing the geometry of the flow part to achieve non-cavitating flow in the flow part and maximum hydraulic efficiency, and, as a result, to achieve better noise behavior of the pump.
