Abstract
Burning behavior of fuel-rich premixed spray was experimentally studied with different fuel volatilities. Overall equivalence ratio of spray jet φsj was quite larger than unity to establish a rich premixed-spray combustion. N-octane, ndecane, and n-tridecane were used as a liquid fuel. With φsjfixed to 12 and with almost the same atomization condition (about 100 μm in Sauter mean droplet diameters d 32), burning behavior depended on the fuel type. An internal flame was observed for n-tridecane but did not appear for n-octane and ndecane. Flame height also depended on the fuel type. The flame height of n-octane was the largest among these three fuels under any atomization condition. When φsjand atomization condition were varied, an internal flame appeared for some conditions of φsjand atomization condition even for n-octane and n-decane. The transition of combustion modes with and without the internal flame was discussed based on fuel volatility.
