AXISYMMETRIC TURBULENT NEAR-WAKE STUDIES AT MACH FOUR: BLUNT AND HEMISPHERICAL BASES.

Abstract

The axisymmetric turbulent near-wakes of two base configurations (blunt and hemispherical) at Mach four were experimentally investigated. A special annular wind tunnel was used which completely eliminated any support interference effects. Detailed pressure measurements were made in all regions of the near-wakes as well as on the bodies. Several flow visualization techniques were used in conjunction with pressure measurements to locate the separation and rear stagnation points. Conventional and color schlieren techniques were used with still and high speed motion picture cameras to qualitatively determine the overall flow patterns. A comparison of the data for the two base geometries indicated a noticeable similarity between the two reattachment processes. (Author)
