Planar imaging techniques such as laser-induced fluorescence are well established and …

The detection of supersonic combustion flow field provides valuable reference information
for the efficient combustion of hypersonic vehicles. From the perspectives of scramjet …

This manuscript describes the wide variety of optical measurement techniques for
characterizing the flow in hypersonic wind tunnels. The introduction briefly describes …

The combustion characteristics of a hydrogen-fueled scramjet combustor were investigated
experimentally and numerically. One nonreacting case (case 1), and two different …

Providing an accurate, representative sample of mass flux across large open areas for
atmospheric studies or the extreme conditions of a hypersonic engine is challenging for …

The characteristics of a hydrogen jet flame in a one-sided divergent scramjet combustor are
investigated using both experiments and large-eddy simulations. Optical observations …

Hypersonic airbreathing engines rely on scramjet combustion processes, which involve high-
speed, compressible, and highly turbulent reacting flows. The combustion environment and …

Supersonic engine development requires accurate and detailed measurements of fluidic
and thermodynamic parameters to optimize engine designs and benchmark computational …

Laser absorption spectroscopy (LAS) tomography is an effective combustion diagnosis
method for its simultaneous imaging of temperature and gas molar concentration. Only …
