Instabilities generated in Mach-6 quiet flow about an axisymmetric cone-cylinder-flare
geometry with a 5∘ half-angle sharp cone were studied in the Boeing/AFOSR Mach-6 Quiet …

Focused laser differential interferometry (FLDI), first introduced in the 1970s, has developed
into a powerful tool for the analysis of turbulent dynamics and fluctuations in fluid flows …

Focused laser differential interferometry (FLDI) measures the phase shift corresponding to
localized fluctuations in the refractive index of a medium. The sensitivity, bandwidth, and …

While designed to suppress disturbances located away from its beam foci, focused laser
differential interferometry (FLDI) is known to have some integration of signals along its …

This work investigates a hypersonic turbulent boundary layer over a 7° half angle cone at a
wall-to-total temperature ratio of 0.1, M∞= 7.4 and R e∞ m= 4.2× 10 6 m− 1, in terms of …

Since the introduction of linear array focused laser differential interferometry (LA-FLDI), its
use has rapidly proliferated as it extends the capabilities of FLDI to multiple measurement …

An analytic methodology is presented to reconstruct the pressure waveform of flowfields with
circular symmetry from the phase shift detected with Focused Laser Differential …

Hypersonic boundary-layer transition onset is commonly characterized in wind tunnel
experiments by measuring the surface heat transfer rise above the laminar level …

This paper presents a computational study of double focused laser differential interferometry
(D-FLDI) measurements related to the second (Mack) mode instability. High-fidelity direct …

A colinear focused laser differential interferometer (FLDI) and self-aligned focusing schlieren
