Recently, drastic urbanization is making building forest in urban area. This phenomenon is causing various problems such as Heat Island, pollutant stagnation and gust. Especially, deformed wind by buildings makes severe problems in wind environment of pedestrian level. To solve this problem, wind tunnel test and CFD(Computational Fluid Dynamics) simulation are used. CFD simulation methods are widely used because of its convenience for time and cost. To properly predict wind environment of pedestrian level in urban multi-residential building with CFD, the boundary condition for simulation should be set in correct. And tree or small structure such as sign and car going road are considered in the CFD simulation. But there is no guideline of CFD simulation for wind environment analysis of pedestrian level in Korea. Because of that, result of CFD simulation is not secured accuracy and reliability.
Therefore, this paper is to discuss the oversea"s CFD guideline for wind environment. Then field measurement and CFD simulation were accomplished to compare wind velocity in multi-residential building block in urban area. In CFD simulation, modeling was performed based on AIJ CFD guideline and 12 case studies were done. The main variable is influence of inlet wind profile(power law) on wind environment, roughness length and canopy model. As a result, exponent 0.15 in power law of wind profile with application of Canopy model for tree effect was more appropriate than general urban wind environment simulation using only exponent 0.33. Based on the result of this paper, exponent 0.33 is usually used for inlet wind profile(power law) in urban area, but exponent can be changed according to surround of analysis area. And a variety of effect, for example tree effect or topography should be considered in CFD simulation.
