Abstract A method to evaluate the properties of turbulent flow in proximity to the vehicle
and close to the ground surface has been elaborated. Numerical simulations have been
performed on the basis of the Unsteady Reynolds-averaged Navier-Stokes equations
(URANS) written with respect to an arbitrary curvilinear coordinate system. These
equations have been solved using the Spalart-Allmaras differential one-parametric
turbulence model. The method of artificial compressibility has been used to improve the
coupling of pressure and velocity in the framework of a finite volume approach. Time-averaged distributions of pressure fields, velocity components, streamlines in the entire area
and near the tractor-trailer, as… More >
