The present study compared the prediction accuracy of three CFD software packages for simulating a airflow over real terrain: 1)Meteodyn WT (turbulence model: k-L RANS), 2)WindSim (turbulence model: RNG k-ε RANS) and 3)RIAM-COMPACT【○!R】 (turbulence model: the standard Smagorinsky LES), which has been developed by the lead author of the present paper. The results from the simulation with RIAM-COMPACT【○!R】 were compared to those from two commercially-available CFD software package (Meteodyn WT and WindSim) and were found to be in good agreement.
