Low-order modelling of the wake dynamics of an Ahmed body [PDF]
Journal of Fluid Mechanics, 2021 We investigate the large-scale signature of the random switches between two mirrored turbulent wake states of flat-backed bodies. A direct numerical simulation (DNS) of the flow around an Ahmed body at a Reynolds number ($Re$) of 10 000 is considered.

Study of the automotive aerodynamic performance affected by entrance structure of forecabin
Energy and Built Environment, 2021 Recently, the requirement for cooling capacity decreased when the driving energy changed from liquid fuel to lithium batteries. Therefore, the structure and location of the forecabin could be adjusted based on the aerodynamic performance.

Large Eddy Simulation with wall functions of Ahmed body
Journal of Physics: Conference Series, 2021 Abstract Large Eddy Simulation with Wall Function (WFLES) is known to be a cheap alternative to classical LES methods for simulation of flow where large and complex computational meshes are typically required. This makes it attractive for engineering applications.

The Effect of Single Dielectric Barrier Discharge Actuators in Reducing Drag on an Ahmed Body
Fluids, 2020 The feasibility of a single dielectric barrier discharge (SDBD) actuator in controlling flow over an Ahmed body, representing a simplified car model, has been numerically and experimentally investigated at Reynolds numbers of 7.68×105 and 2.25×105.

Lateral Vortex Dynamics behind Ahmed body [PDF]
PAMM, 2010 AbstractThe flow‐field in the wake of Ahmed body was studied experimentally. The study is oriented on unsteady behavior of the lateral vortex pair arising in the wake as well as on the wake itself. The time‐mean characteristics of the wake flow are presented. The dynamical behavior of the longitudinal vortex pair is studied in details.
