Description
Urban road tunnels can be a solution to mitigate traffic nuisances but still contribute to atmospheric pollution. This research assesses the environmental impact of tunnel infrastructure, focussing on air quality. Conventional one-dimensional calculation methods, while valuable, often rely on assumptions for parameter estimation. To overcome this limitation, we propose tips for parameter estimation using three-dimensional Computational Fluid Dynamics modelling. We analyse different modelling methods and compare with one-dimensional models to enhance accuracy for predicting tunnel conditions. Initial results include successful simulations of basic tunnel geometries, traffic, and ventilation, serving as fundamental building blocks for larger infrastructure projects and guiding future research endeavours.
