Focused laser differential interferometry (FLDI) and its relative two-point focused laser
differential interferometry (2pFLDI) are completely non-intrusive (ie seedless) optical …

In this paper, aerobreakup in the stagnation region of high-Mach-number flow over a bluff
body is studied with experiments and computations. Water drops of diameter 0.51–2.30 mm …

Acetone tagging velocimetry (ATV) with nominally 1% mole fraction acetone seeding was
conducted in a shock-tunnel-generated hypersonic turbulent boundary layer over a hollow …

Characterization of the thermal gradients within supersonic and hypersonic flows is
essential for understanding transition, turbulence, and aerodynamic heating. Developments …
