STAR/KINetics: a new tool for reacting flow analysis
CD-adapco and Reaction Design, Inc. have recently released 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 CHEMKIN®, 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, 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

the slab as it moves through the chamber, which is open at both
sides. Colors represent flame temperature with maximum (red) being
2370 K. The initial condition is flow at 298 K. (Reaction mechanism
