Quick Links. CHEMKIN-CFD is a plug-in chemistry solver that can be linked to other computational software packages, such as ANSYS’ FLUENT CFD software, to add accuracy, speed and stability to calculations using finite-rate, multi-step reaction kinetics. Detailed reaction kinetics are frequently required to represent combustion and materials process reactions accurately. Such accuracy typically means use of multi-step reaction kinetics. However, using detailed kinetics often causes problems for other software simulation packages, because of computational stiffness, where small changes in one variable may cause large changes in another. In the past, stiff chemistry simulations were characterized by long computational times and unstable solutions that often did not converge.

The library supports the CHEMKIN data format and a native script for defining complex gas mixtures. Nature is written in C# and does not depend on any third party tool.
CHEMKIN-CFD tackles these challenges through advanced and more accurate numerical methods, allowing you to incorporate more detailed kinetics descriptions into your simulations. CHEMKIN-CFD brings the chemistry-solving speed and accuracy of to other simulation environments, providing solution stability and remarkable reductions in computation time, compared to embedded chemistry solvers. Recently the CHEMKIN-CFD speed of calculation has also been even further improved, as shown in the figure below, where a speed increase of up to a factor of five has been observed compared to previous versions of CHEMKIN‑CFD. Furthermore, a major breakthrough in the underlying technology of CHEMKIN-CFD ensures computation times are nearly linear with species count.
Since the computational performance benefit increases with the size of the mechanism, the use of fully detailed or skeletal chemistry is now practical in a commercial engine development cycle. Mechanisms Included with CHEMKIN-CFD for ANSYS FLUENT.
Chemkin-II: A Fortran Chemical Kinetics Package for the Analysis of Gas-Phase Chemical Kinetics. DE90000917 Publication Date 1989 Personal Author Kee, R. J.; Rupley, F. M.; Miller, J.
Page Count 132 Abstract This document is the user's manual for the second-generation Chemkin package. Chemkin is a software package whose purpose is to facilitate the formation, solution, and interpretation of problems involving elementary gas-phase chemical kinetics. It provides an especially flexible and powerful tool for incorporating complex chemical kinetics into simulations of fluid dynamics. The package consists of two major software components: an Interpreter and Gas-Phase Subroutine Library. The Interpreter is a program that reads a symbolic description of an elementary, user-specified chemical reaction mechanism. One output from the Interpreter is a data file that forms a link to the Gas-Phase Subroutine Library.
This library is a collection of about 100 highly modular Fortran subroutines that may be called to return information on equation of state, thermodynamic properties, and chemical production rates.
