The development of water current turbine at Fluid Machinery Laboratory FTMD ITB is starting with searching numerical simulation model at ANSYS 12.1 using NACA0018 blade profile comparing with experiment and carry out that the Reynolds Stress Model is adequate between simulation and the experiments.
The numerical simulation at the flow velocity of 0,4 m/s give CP =0,39 at TSR=3,2 but at the experiments measurement give CP =0,35 and TSR= 3,88.
Other experimental case at flow velocity 0,6 m/s give CP =0,38 at TSR=2,18 the experiments and simulation result different is due to the friction loss of the transmission.
Equipped by NACA0018 optimized, the three parallel current water turbine with concentrator channeling device numerical simulation at velocity V=0,4 m/s produce CP =0,64 at TSR=2,97 and at Velocity V=0,6 m/s produce CP =0,51 at TSR=3,35.
