In recent years, the concept of vehicle platooning has gained widespread attention for its
highly efficient road usage and lower fuel consumption. However, the aerodynamics of
vehicle platoons travelling in a tunnel are not well understood, even though more and more
road tunnels have been built to alleviate the traffic congestion problem. This paper presents
a detailed study of the aerodynamic flow created by a long lorry platoon running through a
tunnel, conducted via a combination of model-scale experiments and Improved Delayed …
