Reaction Design Optimizes CHEMKIN-CFD for ANSYS FLUENT 13

Detailed Chemistry Supported by CHEMKIN-CFD Enables Accurate Simulations for ANSYS Users

SAN DIEGO — (BUSINESS WIRE) — August 31, 2011Reaction Design®, a leading developer of combustion simulation software, is pleased to announce that the CHEMKIN-CFD™ module for simulating detailed chemistry in multi-dimensional reacting flows is now optimized for use with ANSYS FLUENT 13. CHEMKIN-CFD is used by more than 100 organizations worldwide and is available to ANSYS FLUENT licensees at no charge.

Computational fluid dynamics (CFD) is an integral part of the design process in applications that involve chemically reacting flows, but incorporation of detailed chemistry into simulations has been limited due to the computational speed and robustness of the conventional chemistry solvers available in today’s CFD packages. CHEMKIN-CFD addresses the problem of the computational stiffness of CFD by employing proprietary solution algorithms that speed time-to-solution and couples the chemistry and the flow. In addition, it provides solution stability in situations where traditional CFD approaches lack accurate chemistry and are limiting the usefulness of results.

Based on the proven chemistry solving power of CHEMKIN-PRO technology, CHEMKIN-CFD features an advanced chemistry simulation technology that efficiently and robustly couples accurate chemical kinetics to flow simulations. CHEMKIN-CFD for ANSYS FLUENT 13 supports both serial and parallel operation and, in addition to working with the Laminar/Finite-Rate option when solving for gas-phase chemistry, it also supports the FLUENT EDC turbulent-kinetics interaction model. The EDC model provides support for turbulence-chemistry interactions with detailed chemical reaction mechanisms. Once installed, CHEMKIN-CFD can be invoked from a menu option in ANSYS FLUENT.

“The energy, transportation, and materials processing sectors are expanding into new frontiers, which often include challenges such as extreme environments, or radical changes in the scale of operations,” said Bernie Rosenthal, chief executive officer of Reaction Design. “Standard analysis methods do not demonstrate the effects of these changes with sufficient resolution. There is an increasing need for accurate simulation that supports higher complexity and greater chemistry detail. When incorporated into design workflows, CHEMKIN-CFD allows ANSYS FLUENT 13 users to enhance products, reduce development costs, and improve speed to market.”


CHEMKIN-CFD is available today, and license files may be obtained from Reaction Design for up to four free processes. For more information, please visit the  license request page.
