Studies on wind flow are received a huge interest in recent decades. Wind is known as a clean source of energy.  Moreover, it plays a great role in urban ventilation to control air pollution. Therefore, wind flow simulations around single or complex buildings are raised up in recent years.  My colleagues and I made several wind flow simulations.  These simulations are conducted with OpenFOAM solver simpleFoam which is a stead-state solver. OpenFOAM supports a wide class of turbulence models. Different turbulence models are examined in these simulations to find the best result with experimental data. My experience shows kOmegaSST is the most suitable RANS turbulence model for simulation of wind flow.

A brief report of our simulation is presented below:
