Corrugated, hydrophilic particles with diameters between 30 and 150 microm are found to cause cavitation inception at their surfaces when they are exposed to a short, intensive tensile stress wave. The growing cavity accelerates the particle into translatory motion until the tensile stress decreases, and subsequently the particle separates from the cavity. The cavity growth and particle detachm...

The study of cavitation inception in liquids rarely yields reproducible data, unless special control is taken on the cleanliness of the experimental environment. In this paper, an experimental technique is demonstrated which allows repeatable measurements of cavitation activity in liquid-particle suspensions. In addition, the method is noninvasive: cavitation bubbles are generated using a shock...

Unresolved pressure fluctuations at the sub-grid scale (SGS) level of large eddy simulation (LES) or Reynolds-averaged Navier–Stokes computations affect cavitation inception predictions, as SGS low pressures are simply ignored. We present a framework to take unresolved flow into account. Representing canonical turbulence, in this paper, homogeneous isotropic turbulence (HIT), fluctuations, and ...

The multiphase flow in oil hydraulic systems has a very significant effect on the correct operation of system. Air can be found various states systems, while free entrained air form bubbles potential to most problematic. It especially affects compressibility liquid resulting reduced stiffness actuators mechanisms then do not achieve fast response and precision movements depending input control ...

Cavitation is in most cases harmful and undesired phenomenon in fluid power systems. When actions for preventing cavitation are considered, it is essential to recognise the existence of cavitation and location of cavitation inception point. In fluid power components and systems cavitation can occur in various locations where the access for measuring instruments is limited. Therefore, the existe...
