The Near-Wall Flow Analysis Using Wall Function in LES Code(FDS5)
Wall function을 이용한 LES code(FDS5)의 벽 근처 유동해석
Abstract
Recently developed FDS5 CFD code has employed a near-wall flow treatment method which is Werner-Wengle wall law provided by NIST(National Institute of Standards and Technology). In this study, the wall law has been verified against DNS(Direct Numerical Simulation) data in the parallel plate. The
본 연구에서는 가장 최근에 NIST(National Institute of Standards and Technology)에서 LES(large eddy simulation)기법을 사용하여 개발한 3D 화재유동 해석용 FDS5의 중요한 기능 중 Werner-Wengle wall law의 성능을 평가하기 위하여 평행 평판에서의 유동을 조사하였다. 격자 형성을 위하여
