We present an overview of the aerodynamics of heavy vehicles, such as tractor-trailers, high-
speed trains, and buses. We introduce three-dimensional flow structures around simplified …

The performance of bridges under strong wind and traffic is of great importance to set the
traveling speed limit or to make operational decisions for severe weather, such as …

We investigate a hierarchy of eddy-viscosity terms in proper orthogonal decomposition
(POD) Galerkin models to account for a large fraction of unresolved fluctuation energy …

This study presents the results of an experimental analysis of the unsteady features of the
flow around the rear part of an Ahmed body with rear slant angle of 25°. This analysis …

This paper presents an investigation of RANS and DES models for the Ahmed body with 25°
and 35° slant angles. The Reynolds number, based on the height of the model and the …

Large-eddy simulation (LES) is made of the flow around a generic train model at two
different yaw angles of 90∘ and 35∘. The Reynolds numbers, based on the freestream …

The structure of the turbulent flow over a simplified automotive model, the Ahmed body (SR
Ahmed and G. Ramm, SAE Paper No. 8403001, 1984) with a 25 slanted back face, is …

The flow around a finite circular cylinder with a height-to-diameter ratio of 6 was studied
using large eddy simulation (LES). The cylinder was mounted on a ground plane where a …

The turbulent flow past a simplified Intercity-Express 3 high-speed train at R e H= 6× 10 4 is
investigated by a combination of wind tunnel experiments and numerical simulations using …

This course material is used in two courses in the International Master's programme Applied
Mechanics at Chalmers. The two courses are TME226 Mechanics of fluids (Chapters 1-10 …
