The environmental problem and related energy problem are recently the serious problem all over the world. The renewable energy is now highlighted as one of the solution to the problem. The possible use of ocean current as an energy resource begins to draw attention in the renewable energy. In this paper, horizontal axis ocean current turbine performance estimated by Computational Fluid Dynamics is carried out. The numerical estimation method is able to calculate not only a turbine performance characteristics but also turbine with shroud (the collection device) performance characteristics. This method is validated by comparing with experimental results.
