Abstract:

This report covers a literature survey on the status of present knowledge on supersonic diffusers. Three types of diffusers are examined wind tunnel diffusers, ramjet inlets, and supersonic ejectors. No systematic study on wind tunnel diffusers has been found. The results obtained in specific studies, made in conjunction with the design and installation of a number of wind tunnels, show that 100 of normal shock recovery is obtained for M less than 10. Some systematic work exists for ramjet diffusers, with most of the attention being paid to external compression configurations. For supersonic ejectors, comprehensive studies have been made, and useful empirical design methods are available.
