Abstract The process of designing, manufacturing and operating automotive products in modern conditions is unthinkable without the introduction of computer technology at all stages of the life cycle. One of the key tasks in this case is to confirm the compliance of the product being developed with the requirements imposed on it using validated computational models at the earliest stages of design. The article uses several examples to show the experience of using computational studies of the aerodynamic characteristics of vehicles and their components. The obtained calculation results are compared with the available experimental data. Recommendations have been developed to improve the accuracy of calculations for estimating fuel consumption.
Keywords wheeled vehicle, WV, flow velocity, aerodynamic drag coefficient, pressure distribution, validation
