The effect of turbulent wind-tunnel-wall<? TeX 2pc 0pt?> boundary layers on density change measurements obtained with focused laser differential interferometry (FLDI) was studied …
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 …

An exact analytical method for recovering density disturbance spectra in multi-frequency, multi-dimensional fields from focused laser differential interferometry (FLDI) measurements …
This work discusses the design, measurement, and simulation of an oscillating shock- wave/boundary-layer interaction on a flat plate at Mach 5.8 and R e∞= 7× 10 6 m− 1. The …
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 …
