Combustion Rate of Solid Carbon in the Axisymmetric Stagnation Flowfield Established over a Sphere and/or a Flat Plate

Figure 7

Combustion rate as a function of the surface temperature, with the velocity gradient taken as a parameter: (a) in airflow with the H₂O mass-fraction 𝑌_A,∞=0.003; (b) in oxidizing-flow with 𝑌_O,∞=0.7 and 𝑌_A,∞=0.0002. Data points are experimental results [34, 59, 63] in airflow and those [34] in oxidizing flow; curves are calculated by use of the explicit combustion-rate expressions.
