Non-condensable gas mass transfer during cavitation
Abstract
In naval hydrodynamic, non-condensable gases are typically dissolved in water; this affectscavitation inception compared to pure wat er. While models have been developed to capture theeffect of non-condensable gases on cavitation, they are still empirical in nature . Recently, Dr.Gomez at Purdue University has developed a model based on Gibbs free-energy that takes intoaccount mass transfer duri ng phase change. While the model has very little empiricism, there arestill parameters that need to be calibrated through detailed e xperimental campaign. Specifically,we will work on a small scale experimental facility and laser diagnostic to capture mass transfer during laser cavitation with planar laser induced fluorescence to measure concentration ofdissolved oxygen. This step will enable to calibrate the model parameters and set the stage for afuture validation campaign in bubbles. This effort is complimentary to a rece nt DEPSCoR fundingto Dr. Gomez on which Dr. Bardet is a co-PI.
