Cavitation Erosion: Model to Full Scale
Abstract
The overall goal of the project is to improve the Navy#s understanding of cavitation erosion and associated performance loss of naval propulsors, control devices, and surfaces, as well as establish the capabilities in the William B. Morgan Large Cavitation Channel (LCC) to undertake full-scale experiments of cavitation erosion. The objectives of this project are the following: (1) Conduct experimental cavitation erosion studies from the model to the full scale, as well as high-fidelity numerical simulations to better understand, predict, and address cavitation erosion. The team will employ facilities with controlled conditions that range in size fromthe model scale with a test section of less than 1 square inch to approximately full scale with a test cross section of approximately 100 square feet using the LCC. (2) Perform correlation studies using experimental measurements and high-fidelity simulations provide scaling laws and develop simulation tools to capture cavitation regimes. (3) Develop scaling relations of cavitation erosion statistics as a function of material properties and flow conditions in non-dimensional parametric space and develop functional relations between cavitation erosion rate for different test methods. Outcomes of the project will be further understanding of cavitationerosion at the full scale in terms of both the hydrodynamics and the material response to the impact pressures.
