The article presents the results of an experimental study of the sound pressure level (SPL)
caused by a hydraulic power unit with an external gear pump. The study was carried out with …

This article presents computational fluid dynamics (CFD) modeling of the flow processes at a
certain specimen of an external gear pump. The purpose of the developed two-dimensional …

This paper describes the development phases of a numerical-experimental integrated
approach aimed at obtaining sufficiently accurate predictions of the noise field emitted by an …

The article presents an advanced two-dimensional (2D) computational fluid dynamics (CFD)
model of an external gear pump which considers relief grooves. Relief grooves are limiting …

Measurements were carried out on a gear pump mounted on a specific hydraulic circuit
under controlled conditions of installation and operation. The measurement surface had a …
