Numerical Analysis on Aerodynamic Characteristics of Truck

Abstract:

Computational Fluid Dynamics (CFD) is used for the investigation of the aerodynamic characteristics of the truck. The gap between the truck and the container of the heavy truck on its aerodynamic characteristics were simulated by using equations and dynamic mesh method. The finite volume method is used to discrete the governing equations, the second-order up wind difference scheme is adopted for the convection term and the centric difference scheme for the dissipation term. The discretion of time is carried out by a full-implicit time integral scheme. Analysis of the simulated flow fields and the change pattern of the aerodynamic drag under different gap length demonstrate that when the gap length change and the aerodynamic characteristics change. This paper provides a theoretical reference for the development of truck products determining the gap distance between the truck and the container.
