This paper describes the development of a
high‐fidelity computational fluid dynamics (CFD)
model of a three‐blade horizontal axis current
turbine. The CFD model was developed using
STAR‐CCM+ and solves the Reynolds‐Averaged
Navier‐Stokes (RANS) equation for unsteady
flows. Preliminary CFD model results are
compared to laboratory measurements. The
variables being compared include inflow and
wake flow velocity profiles, and performance
coefficients (power, thrust and torque
coefficients) at different tip‐speed ratios. A
preliminary comparison suggests that overall the
CFD simulation results have a good agreement
with the measurements.
