Reaction Design provides CHEMKIN-CFD for free to ANSYS FLUENT users who are looking to improve the accuracy of their flow simulations. Significant run time can be experienced when solving detailed-chemistry simulations as a negative consequence of computational stiffness. This characteristic poses a problem for applications that involve sharp chemistry gradients and/or disparate time scales, either between the chemistry and the flow or within the chemistry itself. Reaction Design’s CHEMKIN-CFD module specifically addresses the problem by working with ANSYS FLUENT software to provide efficient and accurate solution algorithms, assuring robust coupling of the chemistry and the flow.
