INVESTIGATION OF THE INFLUENCE OF THE SPACING BETWEEN THE BORE OF THE THROTTLING SECTION OF THE SHUT-OFF AND CONTROL VALVES ON THE GENERATION OF THE HYDRODYNAMIC NOISE

Autor: V. O. Dorogoichenkov, Mikhail Ermilov, Anna N. Vidyaskina

Publikováno v: Journal of Dynamics and Vibroacoustics. 7:6-10

When designing the throttle sections of the shut-off and control valves, consisting of groups of holes, the question arises about the choice of the distance between the axes of the spacings. The article presents a numerical simulation of the throttli
