Wind environment simulation and assessment of a university campus based on CFD

Based on the natural climate conditions in Guangzhou, this paper simulates and evaluates the wind environment value with dominant wind direction all year round in an area of Guangzhou University Campus close to the highway by the k-epsilon (2eqn) Standard turbulence model of ANASYS software. The information of velocity field, pressure field and the diffusion of solid particle pollutants are obtained through the simulation, and then the outdoor comfort level of the building environment and the pressure distribution of the single building are obtained as well. It is found by the research that the campus wind environment is relatively comfortable. It is conducive to natural ventilation in summer and comfortably walking outside in winter. However, there are obvious low-speed vortices on the back of the building in summer and spring, which makes the particulate pollutants stay in buildings longer. The simulation provides a certain reference for the simulation and planning design of good wind environment in the university campus in the future.
