Post-Processor Options after Running Parameter Studies<br />
2.3.6.3.1 Cluster vs parameter<br />
The first option, the Cluster1C1 vs parameter option, gives the output of most<br />
interest for this problem, i.e., the flame speed, as a function of equivalence ratio. The<br />
flame speed is not shown as an option for single runs, since it is just one data point.<br />
However, for parameter studies, flame speed is a characteristic that can be plotted,<br />
and is shown in Figure 2-21.<br />
The calculated flame speeds are compared with some experimental data 11,12,13 in<br />
Figure 2-21. This figure shows that the flame speed peaks at a stoichiometric ratio<br />
slightly larger than 1. The calculated values seem consistent with experimental data<br />
over the range of equivalence ratios simulated.<br />
