Abstract

Ocean current energy is an energy source that has great potential in Indonesia but is dominated by low current velocity. Many potential locations such as Riau, Boleng, and Mansuar strait only have the maximum current speed by 1.39 m/s, 1.5 m/s, and 1.79 m/s. Therefore, energy conversion technology is needed that is able to exploit the potential of low-speed current energy into electricity. Darrieus turbine is a type of vertical axis hydro turbine that is suitable to be developed in Indonesian waters because it can work at a lower current speed than the other types. To study the Darrieus turbine performance on a low-speed ocean current, numerical modeling based on computational fluid dynamics (CFD) which is validated with experimental results must be done. The numerical validation uses Darrieus turbine experimental data with diameter 0.91 m, chord blade 0.07 m and span 0.7 m. The validation process starts with defining boundary geometry dimension, meshing construction and turbulence model suitable. The simulation is carried out at the current speed of 1.5 m/s with TSR variations. The validation parameter is the torque value that correlates with the coefficient of turbine performance. As the result obtained validation rate with the average error of 7.3%.
