Aerodynamic analysis of some boat tails for heavy vehicles

International Journal of Heavy Vehicle Systems (IJHVS), Vol. 19, No. 2, 2012

Abstract: The aim of this paper is the aerodynamic study of the use of boat tails to reduce the aerodynamic drag coefficient in heavy vehicles. There are some improvements and some patents that improve the aerodynamic efficiency of the vehicle and the fuel consumption, but there are no experimental or numerical analyses of this benefit. This paper analyses some of these improvements using numerical tools and comparing the results with the results of the vehicle without them. To make the numerical analysis, the CFD methodology, using FLUENT, has been used since it allows simulating some geometries and modifications of the geometry.
