Heterogeneous burning in a diverging reactor

Abstract

Experimentally determined pressure profiles in a diverging reactor have been used to estimate effective mean drop diameters and size distributions at the injector end. The available results may be correlated in terms of two simplified models using (a) a uniform mean drop size for the spray and (b) a generalized size distribution of the Rosin-Rammler type. Mean drop sizes of the order of 5 to 10 microns, and effective overall reaction orders between ⅓ and 2 are obtained if the phenomenological burning rate law familiar from single droplet studies is used for heterogeneous burning in bipropellant LOX-RP1 mixtures.
