풍환경 예측을 위한 CFD 시뮬레이션 Mesh Size의 모델링 타당성 검토

다국어 초록 (Multilingual Abstract)

This phenomenon is causing various problems such as wind speed depend on building and building environment, gust. Especially, the gust around buildings layout makes severe problem in wind environment. To solve this wind problem, theory, field measurement, wind tunnel test and CFD simulation are used. CFD simulation method is widely used because of its convenience for time and cost. To predict the wind environment in campus area with CFD, the boundary condition and domain size, turbulence model for simulation should be set in correct. The mesh size has a great influence on the results. So, This paper will be discussed with the CFD results of variety mesh size(Volumetric Control Size)3, 5, 6, 7, 10m.
