Computational study of flow around a simplified car body (2008, methodology): “Results are compared with experimental data [2].”
Cluster-based reduced-order modelling of a mixing layer (2013, background): “The Ahmed body is a generic car model to study the relationship between characteristic flow structures typically arising at passenger cars and their impact on the drag and lift forces (Ahmed, Ramm & Faltin 1984; Lienhart & Becker 2003; Pastoor et al. 2008).”
Adaptation of Eddy-Viscosity Turbulence Models to Unsteady Separated Flow Behind Vehicles (2004, methodology): “Figure 2 shows a sketch of the flow topologies identified by Lienhart and Becker (2003) for 25° and 35° of slant angle.”
Turbulent wake past a three-dimensional blunt body. Part 1. Global modes and bi-stability (2013, background): “…the normalized circulation of one vortex is estimated at around ±0.2 in the present asymmetric case in the plane x∗ = 2.0 and at ±0.8 in the plane x∗ = 1.7 in the 25◦ case from the data of Lienhart & Becker (2003): the intensity of the pair of vortices is then much smaller but remains significant.”
On the need for a nonlinear subscale turbulence term in POD models as exemplified for a high-Reynolds-number flow over an Ahmed body (2013, methodology): “The Ahmed model is used in vehicle aerodynamics as a generic test case that reproduces the important flow structures around passenger vehicles (Ahmed, Ramm & Faltin 1984; Duell & A.R. 1999; Spohn & Gillieron 2002; Lienhart & Becker 2003).”
Hybrid LES/RANS methods for the simulation of turbulent flows (2008, background): “Up to an angle of about 30 of the slant, reattachment occurs at some position on the slant substantially increasing the drag [8,9].”
