soy methyl ester flames were about 70 % the size of diesel soot. More knowledge of
the soot particle properties formed during PME combustion is needed to better
understand the properties of PME fl ames.

5.5 In-Flame Species Concentration

The oxygen concentration in the fl ames at 25, 50, and 75 % fl flame height (FL) is

presented in Fig. 8 a c. The oxygen concentration was low near the centerline and

increased to the ambient value toward the edge. In general, the oxygen concen-
tration near the centerline increased with downstream distance due to entrainment
