Aerodynamic analysis of railway wagon on drag coefficient

Aerodynamics play a major role in transport. When speed increases aerodynamic factors come into existence. By altering the design in an aerodynamic way, it can lead to better efficiency. This paper presents the effect of aerodynamic parameters on the wagon. The analysis was carried out on the existing and modified geometries using ANSYS Fluent 18.1softwareconsidered in the static ground conditions with the wind flowing at zero yaw angles. It was found that the coefficient of drag (C d ) is reduced by 17.7% for the modified wagon with the realistic wagon on an average.
