Abstract

An experimental and theoretical study of the onset of cellular instabilities on spherically expanding flames in mixtures of hydrogen and propane in air at elevated pressures was carried out. Critical conditions for the onset of instability were measured and mapped out over a range of pressures and mixture compositions. An asymptotic theory of hydrodynamic and diffusional-themal cell development on flames in mixtures comprised of two scarce fuels burning in air was also formulated. Predicted values of Peclet number compared favorably with experimentally measured values. This is an abstract of a paper presented at the 30th International Symposium on Combustion (Chicago, IL 7/25-30/2004).
