Chapter 2: Combustion in Gas-phase Processes
If particles exist in the inlet streams, their size moments can be provided in the
Dispersed Phase tab of the Stream Properties panel. Figure 2-62 shows the
Dispersed Phase tab for inlet streams.
The values of high particle-size moments can become very large so sometimes the
absolute tolerance suitable for species mass fractions might not work well for those
high moments. Therefore, the Particle Tracking Module allows the tolerances for size
moments solutions to be given explicitly for the steady state PSR model. The
tolerances for particle size moments can be specified in the Solver window, as shown
in Figure 2-63.
Once all model parameters, initial/guess conditions and inlet stream properties are
set, the JSR/PFR simulation can be launched from the Run Model window like any
other CHEMKIN project.
