FDS와 PIV 기법을 이용한 평행평판에서의 유동분석

초록

A numerical analysis of turbulent flow on a parallel plate was conducted using LES(Large Eddy Simulation) of FDS (Fire Dynamics Simulator) code. The FDS code has been built in NIST for simulation of fire dynamics. The parallel plate length of x direction was 1m, length of y direction was 1m, and height of z direction was 6m. x direction was applied for the periodic flow condition to form infinite plate flow. y direction was applied for a symmetric condition and z direction was a wall condition. The total grid was 32×32×32 and two cases of Re (49,000 , 89000) are investigated to compare with LES and PIV data. The mean velocity profiles was compared with the results of the FDS code and PIV data. It showed that mean velocity profile of the FDS code and PIV data were agreed well.
