An attempt to present and evaluate theoretical and experimental developments in the fluid mechanics of hypersonic wakes since January 1965. Areas receiving emphasis include work done to determine the flow characteristics in the fluid expansion after separation, in the free shear layer, and in the base, recirculation, and recompression regions; work on the mechanism of transition from laminar to turbulent flow in the wake; work on the statistical properties of the turbulent intermittency region at the edge of the turbulent wake core; and work related to understanding the chemistry of production and removal of free electrons in the presence of compressible wake turbulence. 36 pp. Refs.

This report is part of the RAND Corporation Paper series. The paper was a product of the RAND Corporation from 1948 to 2003 that captured speeches, memorials, and derivative research, usually prepared on authors' own time and meant to be the scholarly or scientific contribution of individual authors to their professional fields. Papers were less formal than reports and did not require rigorous peer review.
