초록
A Coanda effect which is known to provide a high lift in a high drag condition has been applied to a flapped rudder of a ship. Model experiments and numerical simulations on the Coanda effect of the flapped rudder have been carried out at various situations and the results are compared to each other. It I found that a remarkable increase in the rudder force occur due to the Coanda effect and that the results ould be utilized for the design of a high-lift rudder system.
