Double, Triple, and Tetra-Brachial Flame Structures around a Pair of Droplets In Tandem

摘要

The multiple flame structures for a pair of droplets in tandem in hot convective flows are analyzed numerically, by employing a body-fitted technique in association with a non-orthogonal curvilinear coordinate system. For selected droplet spacing and Reynolds numbers, three flame structures, including the double, triple, and tetra-brachial flames, are identified at specific ambient temperatures and droplet size rations.
