The Vulnerability Analysis of FDS code for Fire-Driven Flow Simulation in Railway Tunnel

초록

This research carried out a comparative analysis of the results of RANS and DNS (Direct Numerical Simulations) in a space surrounded by walls to verify the performance of FDS in the same area. As for the turbulence model of RANS, the AJL model [1], a recently developed non-linear turbulence model, was used. Also, for comparison with the results of DNS, the data from Moser et al. [2] was used.
