6. 4. Numerical and Experimental Investigation of Hydrodynamic Mechanisms in Erosive Sheet Cavitation

   Author : Mohammad Hossein Arabnejad Khanouki; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Paint test; Numerical simulation; High speed visualization; Shedding behavior; Hydrodynamics mechanisms of cavitation erosion iii; Sheet cavitation;

   Abstract : Cavitation erosion is one of the limiting factors in the design of hydraulic machinery as it is associated with the reduction in the operating life-time of a hydraulic machine and a significant increase in maintenance cost. In order to be able to design a hydraulic machine with a low risk of cavitation erosion, understanding the hydrodynamic mechanisms controlling the cavitation erosion is of great importance.
