Marine Current Numerical Simulation in the Lembeh Strait, North Sulawesi, Indonesia

Abstract

This paper presents a numerical simulation to describe the velocities of marine current in the Lembeh strait, North Sulawesi, Indonesia. These velocities were used to make the turbine profile in the marine current turbines. The RANS calculations were performed in its modelling. The turbulence model using the 3D mixing-length model for shallow water flows that the vertical velocities are small. It’s found the marine current velocities can be used to design of the marine current turbines in the power plant installation. The power density maximum capacity in the small zone of Lembeh strait by the numerical measurement result is 82.11 kW/m2 which enable to the power plant installation in the future.
