A Simplified Method for the Model of Building Groups in CFD Simulation
As a widely adopted technology in the analysis of wind environment in recent years, computational fluid dynamics (CFD) has been playing an increasing important role in ventilation simulation around buildings. However, CFD occupies excessive computing resources when simulating large-scale building areas, which reduces its efficiency. This study proposes a solution by developing a framework to simplify the model of building groups in urban in CFD simulation, which is to find a solution to combine the models of different buildings when modeling. Through the analysis of the factors influencing wind environment around buildings, five parameters (L, W, H, B, and D) are selected as control parameters to measure whether two same cuboid buildings could be combined together or not. Then single factor experiment and orthogonal experiment are introduced to CFD simulation to achieve the appropriate ranges of the control parameters to simplify the model of building groups. Hopefully, this study may improve the efficiency of CFD simulation.
