Fluid pulsations can significantly influence behavior of bearings or sealing parts of hydraulic machines and therefore their operation. In this contribution, an analytical approach to solve pressure pulsations dynamics is compared with a computationa

Quarter wavelength resonator provides a mean to create a pressure drop at a specified frequency. Design of hollow cylinder connected radially to a pipe was used and different lengths of this tuned resonator were measured. Correlation with computation

Eigenfrequency of object drops when it is submerged in the water compared to an air exposition. In this article the effect of partial submersion on dynamic properties of steel plate is investigated. Changes differ by a type of particular modeshape

Additional eect of uid on the solid body is often ignored phenomenon. Although it is possible to do an analytic derivation of equations describing additional eects for many various conditions, it can be dicult to solve them. The paper shows pressure

Bulk viscosity is an important factor in the damping properties of fluid systems and exhibits frequency dependent behaviour. A comparison between modal analysis in ANSYS Acoustics, custom code and experimental data is presented in this paper. The mea

The immersed body has different natural frequencies compared to body in vacuum or air. This is one of added effects of fluid on submerged solid. In this work this is studied on steel plate both experimentally and in simulation. Comparison between the

Flexible tubes are often used in hydraulic measurement, be it connection between pieces of hydraulic equipment or an extension from point of measurement to measuring sensor or as a substitute for a different material e.g. biological tissue. Such tube
