A Methodology to Indentify Erosive Collapse Events in Numerical Simulation of Cavitating Flows
Poster (konferens), 2017

In this study, a numerical method based on the EroCav handbook is presented for assessment of risk of erosive, useable in an incompressible simulation model. This numerical method tracks each collapsing cavity and save its kinematic features up to the final collapse. These kinematic features are then used to estimate the erosiveness based on an equation derived from a parametric study on the collapse of spherical bubbles. The proposed numerical method is applied for the cavitating flow over a 3D NACA0015 foil. Erosive collapse events are indentified and their locations are compared with experimental erosion pattern by Rijsbergen et al.[5]. The comparison shows that the proposed model is able to predict the location of erosive collapse in the middle of foil and the areas close to the side walls.
