| Abstract | This paper presents an investigation of airflow over a rugged mountain to find suitable locations for wind turbines. The investigation considers turbulent intensity and inflow angle in addition to wind speed. The area of interest is the mountain around the upper reservoir of Lamtakong Jolabha Vadhana Hydro Power Plant, Nakhon Ratchasima, Thailand. The Lamtakong Wind Turbine Power System is located near the reservoir. Due to the ruggedness of the site, according to the angle of slopes, the existing turbines may be experiencing airflow with high turbulent intensity and non-zero inflow angle. This study uses Computational Fluid Dynamics (CFD) and Wind Atlas Analysis and Application Program (WAsP) to simulate airflow. CFD is used in the final analysis to quantify turbulent intensity and inflow angle. The turbulence model is used, while the roughness height and roughness constant are tuned according to the ground cover. Detailed examinations of cases show that the highest wind speeds do not always occur at the mountain |
