NACA-TN-3668
Preliminary investigation of a family of diffusers designed for near sonic inlet velocities
Year: 1956
Abstract: Tests have been conducted with a series of diffuser shapes defined by empirical equations having constants which are related to the initial boundary-layer thickness. The shapes were designed to provide high pressure recovery at near sonic inlet Mach numbers, and tests were conducted through the mass-flow range with a variety of attached and separated initial boundary layers. Tests were also conducted with two offset ducts and with a variety of surface conditions in the shortest duct.
