Use of Particle Tracking to determine particle size distributions in a gas-particle flow requires identification of a condensed-phase material that may exist in a form that is dispersed within the gas-flow. In addition, you must specify certain properties of the particle "cloud" that will be tracked. This section describes the necessary input to the chemistry-set files, which are needed to establish these properties. Further discussions, of how kinetics rates may be specified to control the particle nucleation, growth, and transformation, are available in Chapter Particle Size-Distribution Tracking of the Chemkin Theory Manual .

Examples are available in the Ansys Chemkin Tutorials Manual to illustrate how required information is presented to the Particle Tracking feature.
