Abstract

A mathematical field model is developed to predict the resultant carbon monoxide level contour around a two-way vehicular tunnel mouth. This achieved by solving a system of recirculation flow equations for the primitive variables using a two-equation turbulent model with three-dimensional effect. The model is applied to predict the dispersion of carbon monoxide in regions located near the tunnel. By assuming that the highway to the tunnel is constructed adjacent to the hillsides, the effect due to the tunnel jet together with a vehicular queue is studied under the action of wind. The predicted results are useful to justify the environmental impact on the residential area constructed near the tunnel mouth.
