This paper presents a fundamental research on the free surface flows near a two-dimensional transom stern by flow visualization tests and CFD analysis. The flow visualization tests were conducted at a small circulating water channel with a two-dimensional ship model and the argon laser sheet light. The computational approach is based on Reynolds-averaged Navier-Stokes' equations considering free surface flow. As a consequence, it was found that the free surface flows near the transom stern were complex and comprised by the interaction between vortex shedding from the stern end and free surface.
