✦ Synopsis

Progress toward extraction of the elusive pressure-density correlation in variable density reacting flows is reported, using a premixed methane-air flame in open surroundings as the test medium. The relationship among density and other scalars is shown. Molecular Rayleigh scattering, laser Doppler velocimetry, and dynamic Pitot barometry are the experimental techniques used. It is shown that the often neglected pressure-scalar correlation is an important quantity in scalar transport and must be taken into account theoretically in ways that differ from past treatment.
