Aero-Optical Measurements in a Heated, Subsonic, Turbulent Boundary Layer

چکیده
A scaling relationship for OPDrms that accounts for the fluctuating total temperature profile within a turbulent boundary is derived from the modified Crocco relation. Experimental data from heated, compressible boundary layers at six subsonic Mach numbers in two wind tunnel facilities are shown to be consistent with the theory. The results show that a temperature mismatch between the freestream and underlying wall has a significant impact on the overall optical aberration.

Aero-optical measurements in a subsonic, turbulent boundary layer with non-adiabatic walls
This paper presents experimental studies of aero-optical distortions due to a turbulent boundary layer over a range of subsonic speeds with the underlying wall both heated above and cooled below the adiabatic wall temperature. A statistical scaling model, based on Extended Strong Reynolds Analogy is derived and shown to correctly predict experimentally-observed results. The temperature mismatch...

This paper describes a recent investigation of aero-optical properties for subsonic turbulent boundary layers on a flat plate. Laser propagation through the boundary layer at several oblique elevation angles, Mach numbers, and boundary layer displacement thicknesses was investigated. A simple model is proposed that incorporates the oblique angle dependence into an existing scaling relationship....
