Design of Effective Tunnel Ventilation System using Computational Fluid Dynamics

Abstract

A realistic model of a naturally ventilated tunnel with side ducts is analyzed by Computational Fluid Dynamics. This study accounts for the different temperatures of heat sources and the different domains as the phenomenon of smoke marching in the longitudinal direction is captured. The study accounts the domain to be air domain, and then CO domain. The effect of varying the heat intensity with the marching of smoke is analyzed in the research. Critical parameters like air flow direction and velocity of smoke are taken into account. The paper mainly focuses on temperature distribution, modelling the problem as a convection problem.
