Identification of sound sources in hydraulic valve
T. Blejchař, M. Kozubková
pages 26 - +11p., full text

The paper deals with numerical simulation of flow in hydraulic valve. For numerical modeling finite volume method applied to momentum equations of real fluid for laminar and turbulent flow respectively (Navier-Stokes equations and Reynolds equations respectively) was used. High frequency unsteady flow was generated in throttling area and was eliminated by their modification, low frequency unsteady flow was generated in piece and was shift down after modification.
