Numerical Study on the Influence of Air Bubbles around the Ship Hull on the Propulsive Efficiency

Injecting air at the ship bottom to create a mixed layer of seawater and air bubbles between the hull surface and seawater is well known as an efficient energy saving technique to reduce the frictional drag of ships. Various studies have been conducted to promote the efficiency of frictional drag re...
