Abstract
A non-contact measurement method for wall friction distribution using oil film has been already proposed by the authors. The present paper describes the result of the application of the method to the fore part of small ship model. Since the boundary layer near the bow is generally very thin, it is impossible to use the normal device for measuring the wall friction, such as Preston tube. This method enable to measure the wall friction distribution and limiting streamline. The effect of turbulent stimulator is also examined through the experiment.
