摘要:Abstract(#br)Recent experimental investigations in the wake of an idealised car model – the Ahmed body showed the existence of two stable wake states: flow state I, where the flow is fully separated over the back slant of the Ahmed body, and flow state II, where the flow init...

摘要:Abstract(#br)Ahmed body is a simplified vehicle model which retains important features of real ground vehicles. Present study aims to investigate effects of rear slant angles ( α = 25°, 30° and 35°) on time-averaged and instantaneous flow characteristics downstream of the Ahmed body...

摘要:... In this paper, effects of the diffuser angle on the aerodynamic behavior of the Ahmed body have been investigated for low Reynolds number flows. Numerical simulations were performed by solving the Reynolds Averaged Navier-Stokes (RANS) equations combined with different turbu...

摘要:Abstract(#br)Through numerical simulations, the interaction between the longitudinal c-pillar vortices and the flow over the rear slant surface is established for an Ahmed - body geometry as its aspect ratio is varied. In turn this affects the flow structure and topology of the n...

摘要:Abstract(#br)The flow around the Ahmed body at varying Reynolds numbers under yawing conditions is investigated experimentally. The body geometry belongs to a regime subject to spanwise flow instability identified in symmetric flow by Cadot and co-workers (Grandemange et al.,...

摘要:... It consists in analyzing the effect of canceling the separation on the rear slant of an Ahmed body (inclined at 25°) on the different structures developing in the wake. In order to better understand the flow features when canceling separation by means of flow control for d...

摘要:... Numerical simulations are performed for two simplified vehicles: a slanted-back Ahmed body at Re = 30,000 and a squared-back Ahmed body at Re = 300,000. A comparison of the resolved and modeled physical flow scales is made with corresponding LES and experimental data for a b...

摘要:Abstract(#br)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 upstream velocity, is 7.68× 10 5 . Two RANS (Reynolds Averaged Navier–Stokes) models a...

摘要:... A conductive Ahmed body is incorporated at the center of the enclosure. The effects of several parameters such as Rayleigh number (10 3 ≤ Ra ≤ 10 5 ), volumetric fraction (0 ≤ φ ≤ 0.05) of nanoparticles, angle of inclination of cavity (0° ≤ α ≤ 180°) and th...

摘要:Abstract(#br)A numerical simulation based on the Large eddy simulation method is carried out on the near wake flow behind a 25° slant angle Ahmed body to analyze and establish a new method to control the near wake flow. An active flow control using a new unsteady jet derived...
