Research Abstract

A fundamental study to enhance performance of a wing under transitional condition, such as a rudder or a fin of a ship, has been conducted. By applying humps or some additional parts on wing, which enhance the wing performance in steady state, wing performance under transitional conditions and its variation given by the parts on the wing have been investigated. Forces acting on a wing that moved in a water flow have been measured in experimental measurements. Numerical simulations of flow around a wing in the similar conditions have also been conducted. Based on these results, variations of wing performance and their elements have been investigated.
