Non-condensable gas mass transfer during cavitation
Abstract
Cavitation is a very complex phase change phenomenon. While progress has been made in its understanding and models are becoming more accurate, there are still gaps when non-condensable gases, which are ubiquitous in naval environment, are present. Dr. Gomez at Purdue University has developed a model based on Gibbs free-energy that takes into account mass transfer duringphase change. While the model has very little empiricism, there are still parameters that need to be calibrated. Specifically, we will work on a small scale experimental facility and laser diagnostic to build a Hele-Shaw cell to simulate mass transfer in a one dimensional geometry and deploy planar laser induced fluorescence to measure dissolved gases concentration. This step will enableto calibrate the model parameters and set the stage for a future validation campaign in bubbles. This effort is complimentary to a recent DEPSCoR funding to Dr. Gomez on which Dr. Bardet is a co-PI.
