This research investigates of the effects of inlet wind velocity and inlet wind direction on airflow around the buildings of Rajamangala
University of Technology Rattanakosin (Salaya), Thailand using Computational Fluid Dynamics (CFD) turbulence models. The evaluation of a CFD model’s performance and validation of its predictions with high-quality experimental data is necessary before the model is used in practice. In this study, there are 2 Models. Model 1 is the simulation for an inlet wind velocity of 0.5 and 1.5 m/s in the west direction. Model 2 is the simulation for an inlet wind velocity of 0.5 and 1.5 m/s in the south direction. The results were found that the
higher inlet wind speeds at the inlet flow boundary would lead to a higher increase in the average speed of air around the building. In addition, the combined wind speed and inlet flow direction were affected to where the maximum wind speed occurs. The data obtained from this study will serve as a future basis for the construction of buildings in the university to provide better natural ventilation.
