| Outline of Final Research Achievements |
A novel numerical simulator to compute local behaviors of sea sprays and entrained bubbles produced by micro ocean wave-breaking processes, based on the stochastic turbulence model, was developed in this study. The model was confirmed to reasonably reproduce heat and gas transfer through advection and diffusions processes via gas-liquid mechanical interactions.
Physical experiments for measuring the size distributions of sea-sprays and bubbles entrained into sea and the thermal radiation on the breaking-waves faces were performed in a wind wave flume. The momentum and heat transfer on the aerated ocean waves were found to be parametrized by the wind wave Reynolds number.The in-situ measurements for sea-sprays and air bubbles in ocean were also performed for characterizing mechanical contributions of the aerated ocean surface to the wave and current field.
