DISPERSION OF CARBON MONOXIDE FROM A VEHICULAR TUNNEL WITH THE EXIT LOCATED ALONG A HILLSIDE

In this article, a mathematical model is described, which can be used to simulate the dispersion of carbon monoxide from a vehicular tunnel with the exit located near a hill under the action of wind. This model is achieved by solving the system of recirculation flow equations using spalding's developed field model. In this model, the general variables are the velocity components and carbon monoxide concentration, with two other parameters, the turbulent kinetic energy, and dissipation rate. Results can be used to show the environmental impact upon residential areas nearby, enabling proper design of the tunnel ventilation.
