Supersonic base pressure and lipshock

Current base flow theories, including that of Tanner (1984), do not explicitly take the effects of lipshocks emanating from the base region into account, despite lipshocks' significant influence on the near wake, and therefore base pressures. Attention is presently given to the basis for the good agreement of Tanner's theoretical values with experimental data. Tanner has implicitly accounted for lipshocks' influence in the ratio of the height of the shear layer-affected wake-shock to the reacting shear-layer thickness. (O.C.)
