Ship drag reduction
WebFeb 1, 2015 · Practical application of microbubble method to ship drag reduction has been actively studied in recent years because of the potential energy savings and the environmental benefits in terms of marine pollution. Kodama et al. (2008) reported approximately 10–15% saving of the total energy consumption for an experimental ship. WebSep 1, 2011 · The wave impact on the cavity shape and drag reduction was estimated with a novel analytical approach that takes into account the air compressibility in the cavity and air entrainment by the water. The model drag was measured in the Naval Surface Warfare Center linear tow tank at different drafts in calm water and in waves.
