The very first step in the simulation of ice accretion on a wind turbine blade is the accurate prediction of the flow field around it and the performance of the turbine rotor.
The paper addresses this prediction using RANS equations with a proper turbulence model.
The numerical computation is performed using a commercial CFD code, and the results are validated using experimental data for the 3D flow field around the NREL Phase VI HAWT rotor.
For the flow simulation, a rotating reference frame method, which calculates the flow properties as time-averaged quantities, has been used to reduce the time spent on the analysis.
A basic grid convergence study is carried out to select the adequate mesh size.
The two-equation turbulence models available in ANSYS FLUENT are compared for a 7 m/s wind speed, and the one that best represents the flow features is then used to determine moments on the turbine rotor at five wind speeds (7 m/s, 10 m/s, 15 m/s, 20 m/s, and 25 m/s).
The results are validated against experimental data, in terms of shaft torque, bending moment, and pressure coefficients at certain spanwise locations.
Streamlines over the cross-sectional airfoils have also been provided for the stall speed to illustrate the separation locations.
In general, results have shown good agreement with the experimental data for prestall speeds.
