Abstract

PASSING MANOEUVRES and crosswind can have significant effects on the stability and fuel consumption of road vehicles. When two vehicles overtake or cross, they mutually influence the flow field around each other, and under certain conditions, can generate sever gust loads that acts as an additional forces on both vehicles. The forces acting on them are a function of the LONGITUDINAL AND TRANSVERSE SPACINGs and of the relative velocity between the tow vehicles. In this paper, the models were designed to study the effects of various parameters such as the LONGITUDINAL AND TRANSVERSE SPACING, the relative velocity and the crosswind on the AERODYNAMIC FORCES and moments generated on the overtaken and overtaking vehicles using Ansys CFX. The AERODYNAMIC FORCES have been predicted by a SST model solution of the Navier-Stokes equations for turbulent flow. The numerical predictions for the evaluation of aerodynamic coefficients agree well with the scaled-down air tunnel experimental work.
