A Study on the Dependence of Air Pressure Distribution on Difference in Breaker Types

Abstract

The structure of gas pressure during wave breaking has not been fully explained. In this study, the distribution of gas pressure during wave breaking for two breaker types was studied by conducting hydraulic experiments and numerical computations. Further, the effects of wave breaking on the gas pressure were considered. As a result, we found that the distribution of gas pressure became symmetric between the front and back of the wave crest when wave breaking does not occur. On the other hand, gas pressure was found to be asymmetric between the front and back of the wave crest when there was wave breaking. Specifically, isobaric contour intervals were found to be smaller in front of the wave crest.
