Simulation of Crosswind Effects on Rail Vehicles

This project has been done to investigate the effects of the aerodynamic forces produce by the crosswind on the static trains. It has been carried out by comparing the available wind tunnel test result taken from a journal with the simulation produced using Computational Fluid Dynamic (CFD) software...
