A slender-bodied vehicle with asymmetrically arranged protuberance generates strong side force due to asymmetric vortices, even at a low angle-of-attack. We investigated effects of the well-known RANS turbulence models [SA-R (C-rot = 0.0, 1.0, and...
Typical launch vehicles feature several surface devices, such as ducts, cameras, and side jet motors. When these protuberances are asymmetrically distributed, an asymmetric vortex is formed around the vehicle, generating a side force. Furthermore,...

To accurately obtain a drag value for slender bodies (e.g., a rocket used in wind tunnel testing), base pressure and cavity pressure are required to be corrected to remove the effect of a sting. As the drag value significantly depends on the corre...
