Abstract

Planar laser-induced fluorescence (PLIF) offers the capability of two-dimensional flow imaging of such quantities as temperature, species concentration and velocity. In difficult environments such as that experienced in a supersonic combustion ramjet (or scramjet), it can be an invaluable tool for examining mixing and combustion processes (see for example Allen et al 1993 and McMillin et al 1995). The imaging is performed by exciting a given molecule (for combustion studies, OH) with narrowband laser length and capturing the resulting fluorescence on a fast-gated two-dimensional detector.
