A key finding is that the entrainment process highly depends on Froude number (Fr) with the entrained air volume linearly proportional to Fr2 . KEY WORDS: Multiphase flow; Air...

... linear methods which could be implemented to find the wave inputs required to predict shoreline erosion. Thin-ship theory was decided upon and implemented to calculate wave resistance and elevation. Results show the thin-ship model to be accurate for all tested ships between Froude numbers of 0.35-0.7...
