Numerical simulation of the aerodynamic interference in traffic flow

Fundamental purpose of realized simulations was the estimation of the size and importance of aerodynamic interference between vehicles moving in a convoy. In the work, it has been mainly focused on the aerodynamic drag and the analysis of its formation for particular vehicles. Main indicators of interference were the changes of aerodynamic drag coefficients of particular vehicles according to the configuration of a convoy, the distance between particular vehicles and the form of bodies. Quite a large number of simulation results has made the base for realization of extensive comparisons and analyses.
