Design of Low Drag Bluff Road Vehicles
TL;DR: In this paper, a three phase approach that uses numerical simulations, scaled wind tunnel experiments and full-scale road testing is used to design a low-drag road vehicle with a trailer underbody flow and tails for the trailer's rear end.
Wind effects on permeable building envelopes: a two-dimensional exploratory study
TL;DR: In this article, an exploratory two-dimensional study on systems composed by an open-gap airtight screen and a rectangular section was performed, where the aerodynamic interference caused by the presence of the screen was investigated, trying to understand the role of each potential influencing factor.

Numerical and physical simulation of axisymmetric streamlining of a staged cylinder with a low-velocity flow of air
TL;DR: In this paper, the mechanism to reduce the frontal resistance to the motion of a staged cylinder of circular cross section and limited length is analyzed on the basis of a numerical solution for the Reynolds equations closed by means of a dissipative two-parameter model of turbulence, and through systematic measurement in wind tunnels.

Interaction Effects on the Drag of Bluff Bodies in Tandem
Anatol Roshko,K. Koenig +1 more
TL;DR: In this paper, the authors studied the flow over two tandemly positioned bluff bodies in close enough proximity to strongly interact with each other, and found that this interaction is often beneficial in that the drag of the overall system is reduced.
