Furfuryl alcohol droplet

The present theoretical model is used here to analyze the entire ignition and combustion process for a single droplet and to examine the eflFects of nonsteady droplet heating and droplet motion relative to the hot gas environment. The computations pertain to a 300 fx furfuryl alcohol droplet with an initial droplet temperature of 295 K, and the conditions for the hot gas environment are taken to be = 1400 K and iVo) = 0.1355 g 02/g air. The rate constants used for the ignition criterion are those determined in Ref. 7. The eflFect of droplet relative motion on ignition and combustion is illustrated in Figures 2-6 as a function of the gas-phase heat and mass transfer mode namely, pure diflFusion, free convection, and forced convection with the droplet relative velocity taken as Vd — Voo = 25 cm/sec.
