After enabling CHEMKIN-CFD, you would not see the reactions under Fluent material panel. All the reactions information are preprocessed and stored by CHEMKIN module. Enabling CHEMKIN-CFD from Reaction Design for laminar reactions, will allow you to use the proprietary reaction-rate utilities and solution algorithms from Reaction Design, which is based on and compatible with their CHEMKIN technology. For Eddy-Dissipation Concept Turbulence-Chemistry Interaction and the Composition PDF Transport model, enabling the CHEMKIN-CFD from Reaction Design option will allow you to use reaction rates from Reaction Design’s KINetics module, instead of the default ANSYS FLUENT reaction rates. ANSYS FLUENT’s ISAT algorithm is employed to integrate these rates. For surface chemistry, with CHEMKIN-CFD, the surface reaction rates are computed from the Reaction Design’s KINetics module.
