A New Tool for Reacting Flow Analysis
Posted Tue November 25, 2003 @11:44AM
Print version Email story Tweet story
News The CD adapco Group and Reaction Design jointly announce the release of STAR/KINetics, a software tool for simulating processes involving both rate-based chemistry and complex fluid dynamics.

STAR/KINetics is a close coupling of STAR-CD, the leading tool for complex flow simulation, with proprietary solvers and components of CHEMKINŽ, Reaction Design's powerful chemical kinetic simulation package. STAR/KINetics allows researchers to seamlessly solve reacting flows with comprehensive treatment of both detailed chemistry and intricate flow geometries, including heterogeneous interaction at gas-solid interfaces. The tool's great strength lies in an unrivalled ability to predict the interplay between fluid transport, heat transfer, and chemistry in applications ranging from materials processing, to combustion, and to chemical manufacture.

CFD analysts who are interested in chemical reactions can now extend their capabilities beyond the simplified reaction descriptions used previously, to a tool capable of including the industry standard, detailed CHEMKIN reaction models. STAR/KINetics incorporates STAR-CD's treatment of a variety of physical phenomena, including sprays, radiation, turbulence and buoyancy, with CHEMKIN's unrivalled treatment of chemical kinetics.

Examples of typical industry processes that can be simulated using STAR/KINetics include:

  • In-cylinder, gas turbine, coal, alternative fuel and catalytic combustion
  • Gasification and pyrolysis
  • Oxidation and dehydrogenation of light alkanes to oxygenates and olefins
  • Reformation of hydrocarbons for fuel-cell applications
  • Selective Catalytic Reduction (SCR) and Selective Non-Catalytic Reduction (SNCR) of NOX
  • Catalytic and non-catalytic exhaust aftertreatment devices
  • CVD, ALD, and chemical etching

"With STAR/KINetics, chemists and engineers can face the challenge of increasing the efficiency of chemical processes and combustion devices while reducing emissions of pollutants from them", says Steve MacDonald, President CD adapco Group. "Traditional approaches using operational or global kinetics descriptions neglect the pivotal contributions of minor species and competing reaction paths to the predictions of chemical composition, emissions, and heat release. For CFD analysts, the ability to include detailed CHEMKIN mechanisms into robust flow analysis has finally arrived" adds Ellen Meeks, Vice President of Product Development, Reaction Design.
