Unmerical Modeling of Isolated n-alkane Droplet Flames: Initial comparisons With Ground and space-Based Microgravity Experiments

摘要

Transient, spherically symmetric, combustion of single and multi-component liquid n-alkane droplets is numerically simulated with a model that includes gas phase d4etailed, multi-component molecular transport and complex chemical kinetics. A compact semi-detailed kinetic mechanism for n-heptane and n-hexadecane oxidation consisting of 51 species (including He, Ar, and N_2) and 282 reactions is used to descaribe the gas phase. Non-luminous, gas phase radiative heat transfer and conservation of energy and species within the liquid Droplet interior are also considered.
