Near-Wake of an Inclined 6:1 Spheroid at Reynolds Number 4000

What is it about?

The 6:1 prolate spheroid at high incidence is a favorable research object in both aerodynamics and ocean engineering communities. It serves as a good prototype for the maneuvering problem of various slender aircrafts and submarines. The wake behind this configuration is characterized by a significant time-averaged side force, and turns out to be complex. By means of direct numeric simulation (DNS), we investigated in-depth the transitional wake behind a 6:1 spheroid at 45-degree attack angle at Reynolds number 4000, in which several new flow phenomena were reported and discussed.
