Three-Dimensional Flow Separations on Aircraft and Missiles

Afterbody vortices of axisymmetric cylinders with a slanted base

“…Similar experiments have been performed by Maull (1980), Xia and Bearman (1983) and Britcher and Alcorn (1991), which have used similar slanted base cylindrical models and reported the same trends in the drag coefficient. Epstein et al (1994) and Peake et al (1972) claimed the absence of a vortex shedding frequency in the vortex pair regime, and similarities in the structure of the flow field were drawn to delta wings. Epstein et al (1994) also concluded that the size and shape of the afterbody vortex was only weakly, if at all, dependent upon the Reynolds number.…”

Wake-Fin Tailoring for Projectile Steering

“…As oppose to at high angles of attack, three-dimensional separation occurs symmetrically at low angles of attack for a long pointed slender body [30]. The ideal position to apply active control for pitching control of slender bodies is normally the aft body.…”

Boundary layers and separation on a spheroid at incidence

“…Among the experimental studies are those of Werle, 1 Wilson,2 Peake et al, 3 Han and Patel, 4 Ramaprian et al, 5 Hayashita, 6 and Meier et al 7 " 1 " Most of the early studies were restricted to flow visualization and, to date, much of the available information is concerned with flow at or close to the surface. Measurements within the boundary layer are quite limited.…”
