The Chemkin Input Manual is designed to serve as a reference to Ansys Chemkin users who require more information about the input parameters needed in defining a chemically reacting flow simulation. In particular, information about syntax and format of chemical reaction mechanism input files, thermodynamic data, and transport-property data are described in detail. In addition, detailed information about all of the input parameters associated with reactor models, including default values and usage guidelines, are included in the Keywords section.

The Ansys Chemkin Interface guides users through problem setup and execution, as well as quick analysis with the Chemkin Visualizer. The operation of the Chemkin Interface and Post-Processing are described in detail in Chemkin Getting Started Guide. In some cases, however, users may wish to work from the command line instead of the User Interface and manually assemble Reactor Model input files. For this purpose, the Chemkin Input Manual describes the necessary syntax and usage of the reactor-input Keywords, as well as a quick reference of what keywords are available for each Reactor Model.

For background information on the equations and theory behind the input parameters, the Chemkin Theory Manual provides further reading. In many cases, equations in the Chemkin Theory Manual are references in the discussions of reactor parameter input Keywords.

In Thermodynamic Data through Transport Database, the syntax and format required for thermodynamic, gas-phase kinetics, surface kinetics, and transport-property input data are described. Description and Properties of Particles has the description of fundamental particle properties for Particle Tracking. CHEMKIN Project Input: Keyword Syntax and Rules provides an overview of the syntax and rules for Keyword input, which make up the Reactor Model input files. Reactor Model input files are ordinarily created by the User Interface but can also be manually assembled for command-line usage. Reference Guide to Project Input Keywords provides a Quick Reference of the Keywords, organized by Reactor Model and other concepts, while Alphabetical Listing of Project Input Keywords contains alphabetical listings of keywords.
