Abstract
The present work showed that steady-state flows around the Ahmed body exist at least for the range Re ⩽ 1350. All the obtained steady-state flows can be classified into six regimes depending upon the number of the reverse-flow regions and the occurrence of separation-reattachment. The reverse-flow regions are formed in the order of the wake flow region, near the front of the body, on the slant surface, on the top, and the side of the body as Re increases. Some parts of local-flow-structures which appear at high Re are also involved in the rather low Re flows.
