Modeling of bubble dynamics at USRS field sites with comparisons to data
Abstract
The overarching goal of this research effort is to use our high-fidelity bubble simulation tools to investigate the bubble entrainment mechanisms in the estuarine fronts observed during the ONR USRS project. It is hypothesized that wave breaking is the primary driver of bubbles and bubble entrainment near estuarine fronts. Utilizing high-resolution simulations, we will directly capture the air entrainment and bubble generation processes. Model-data comparisons will be made to the USRS data set including additional sUAS imagery analysis products, such as quantified wave-current interactions and the occurrence of wave breaking. Outcomes of the project will include: an open archive of the USRS data set, an established powerful multi-scale computational capability for bubbles that features both explicit resolution of waves, air cavity, and large bubbles resolved on a fine grid, as well as physics-based subgrid-scale modeling of bubble clouds containing a wide range of bubble sizes, quantified wave-current interaction around estuarine fronts and the occurrence of wave breaking via sUAS data analysis, verification of model against USRS field data, and forward image modeling (satellite SAR) of the simulated fronts with comparison to USRS data set.
