Abstract

Flame propagation experiments on n-decane spray were conducted in microgravity to study the flame propagation mechanism of spray for less volatile fuels. An electrically heated Nichrome wire ignited the spray just after the Sauter mean diameter (SMD), and the concentration of spray was measured by a laser droplet analyzer. The change of the flame propagation speed with the SMD had a maximum for a constant equivalence ratio. This could be reasonably explained by analogy with the flame spread from a droplet to a neighboring droplet in a droplet array, i.e., the flame spread of a droplet array and the flame propagation speed of spray take a maximum when the spacing between a droplet and a neighboring droplet is approximately equal to the flame radius of the droplet.
