Abstract: CFD (Computational Fluid Dynamics) simulation is the main research method for assessing the wind environment around building complexes. Recent research showed the importance of turbulence models used in simulation and different turbulence models were developed to improve the precision of CFD simulation results. In this paper, a comparison of different turbulence models in simulating wind environment around building complexes is conducted to discuss their precision of simulation in three key elements of engineering application. The recommended turbulence model is determined based on the comparison and the wind environment of a residential district is simulated with the suggestions. Finally, the simulation result is compared against filed measured data, where the results coincide.
