Abstract

Abstract: Almost seventy percent of all goods are transported with the help of commercial vehicles with tractor-trailer combinations. Despite the fact that intensive aerodynamic studies have been taken into account for a few decades within the automotive industry. In theory the engine will only deliver fifty percent of the power to move the vehicle forward as the other fifty percent will be wasted against the significant and contrasting drag force. Computational Fluid Dynamics, often known as CFD, is a very powerful and effective tool which is used in engineering practice to find solutions to aerodynamic problems. The ANSYS Fluent (version 2016) software has been used to conduct the analysis throughout this paper and solidworks (version 2016) software to draw all model used. This article contains an in-depth study involving the usage of NACA aerofoil on the critical area of a trailer to help reduce the drag coefficient and hence exploit the fuel saving potential. Various different NACA aerofoils have been used in the study of the effectiveness of each profile for the given purpose. The best choice of NACA profile concluded from the CFD results is NACA 0012 with five parts attached to the truck trailer.
