Calculation of the Burning Rates of Interacting Fuel Droplets†

Abstract

The quasi-steady (QS) burning rates of interacting spherical fuel droplets are calculated by transforming the equations governing the inter-droplet fields to the Laplace equation and then solving the transformed equations by the method of images. The results of this work indicate that QS interactions can significantly reduce the droplet burning rates even for large droplet spacings. Further, the well known D²-law is found to be only approximately correct when applied to interacting droplets.
