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 …

A focused laser differential interferometer (FLDI) simulation was used to study the sensitivity
of the FLDI technique to a variety of factors. The model takes in a series of density fields and …
