Maximization of ship friction resistance reduction by bubble cluster control

Purpose of Research

Frictional Drag Reduction by Injected Bubbles

We are making continuing effort to improve Particle Image Velocimetry as applying these methods to a variety of flowfields where conventional techniques were impossible or invalid, targeting to clarify the essential flow characteristics in those configurations. Applying this method and the way of approach to solution, we select the research topics that will respond to industrial needs.

Summary of Research

Development of air bubble control technology that maximizes frictional drag reduction

A frictional drag experienced by large ships accounts for approximately 80% of the total resistance the ship experiences. A method for reducing turbulent frictional drag using air bubbles has been developed, which has improved the efficiency of ship navigation speeds and saved energy. We are currently challenging ourselves to develop new technology that maximizes this mechanism. We are looking for talented students to join us in developing cutting-edge technology.
