Rapid transition towards renewable, wind is having potential of 14TW. Flow simulations attracted worldwide scholars to optimize wind power production and wind farms. In present work NREL 3MW wind turbine under k-ε RANS model is simulated at two velocities i.e. 10m/s and 15m/s to calculate the flow and pressure distribution over wind turbine. With these variables velocity magnitude, dynamic pressure, wake effect and turbulent dissipation rate results are generated, compared and analyzed. Accurate results are shown in near wake regions. At 10m/s fluctuations in velocity magnitude are recorded less, which leads to less pressure drop and less intensified wake downstream, The distance covered by 2nd wake is recorded more while at 15m/s there are more fluctuations in velocity magnitude this results more pressure drop and provide favorable conditions for turbulent wakes. The distance of 1st and 2nd wake is recorded almost equal while the 1st wake intensity is more. The computational time by k-ε model require less time and provide good results.
