An Interferometer Study of Air Flow Near the Exit of a Constant Area Duct Followed by a Variable Divergent Section.
Abstract
Fluid properties of both fully-developed, turbulent flow and undeveloped, laminar flow near the exit of a constant area duct followed by a variable divergent section were investigated and compared. Points of flow separation were also compared. A Mach-Zehnder interferometer was used to obtain density data and flow visualization. The fluid properties of the fully-developed, turbulent flow changed more than the undeveloped, laminar flow at the constant area exit as the divergence angle increased. The two regimes of flow appeared to be identical through the divergent section. (Author)
