Simulation Method and Evaluation Strategy of Wind Environment in Urban Center Area

scSTEAM is one of the world’s leading CFD software. Since its debut in 1984, scSTEAM has been widely used in many industries, especially in the fields of construction, civil engineering, air conditioning, HVAC, and electronics. scSTREAM is a generic thermal fluid simulation software based on a structured grid (right angle or cylindrical coordinates). The geometric model suitable for the simulation is often composed of a large number of rectangular components, and any curved surface and slope are approximated by the ladder shape and won’t adversely affect the flow field or heat conduction. For physical applications that accurately predict flow field structures without the need to accurately consider curves and surface geometry, the outstanding performance in terms of meshing and computational speed can be greatly exerted, and is more appropriate for physical and environmental simulations at the building and urban levels.
