Cavitation Erosion: Scaling Analysis and Characterization

Abstract

The goal of the project is to elucidate understanding of cavitation and the material response of cavitation-induced erosion relatedto naval propulsors, control devices, and surfaces. In Phase I of the project, capabilities for full-scale cavitation erosion experiments were established in the William B. Morgan Large Cavitation Channel (LCC). Furthermore, other related model scale experiments for cavitation and material behavior and numerical simulations across scales and fidelity were undertaken to understand, predict, and address cavitation erosion. The objectives of the Phase II project are the following: (1) Conduct experimental and computational cavitation and cavitation erosion studies across scales to better understand, predict, and address cavitation phenomena and material erosion. (2) Investigate the scaling of hydrodynamical and material properties in non-dimensional parametric space by correlatingexperimental measurements and high-fidelity simulations. (3) Assist Naval Surface Warfare Center Carderock Division in the design of Phase II experiments of cavitation erosion experiments at the LCC. Expected outcomes of the project are a better understanding ofcavitation and its erosive properties, characteristics of different materials, and enhanced capabilities for cavitation erosion experiments in the LCC.
