Reaction Design Announces CHEMKIN 3.7.1

Reaction Design has added new Applications and extended the capabilities of existing Applications to significantly enhance the number and types of problems that can be addressed with CHEMKIN. This page contains a summary of the new release.

You can download the full release or contact Reaction Design to request a CD. If you are updating CHEMKIN 3.7, a patch is available also. If you are not a member of our Members Area, you will need to register in order to download CHEMKIN.

Highlights of What's New in CHEMKIN 3.7.1

  • For some applications, the gas inlet flow rate varies with time. An example is a model of engine aftertreatment where the engine-out data is the input to the aftertreatment model. With the latest release of CHEMKIN users can model these problems successfully. The capability is available for a single perfectly stirred reactor (PSR) and PSR network models within the CHEMKIN Application, AURORA.

  • Sensitivity analysis is a useful feature that enables users to determine the sensitivity of species concentration and temperature to gas-phase and surface reactions rates. The transient sensitivity analysis in the latest release is as much as five times faster than Release 3.7. In addition, the user now has more control over the saving of sensitivity analysis results for transient simulations, which streamlines post-processing.

  • Additional new post-processing capabilities include:

    • Key-component conversion percentages, useful for fuel reforming and catalytic conversion calculations
    • Integrated deposition rate, for transient deposition calculations in Chemical Vapor Deposition (CVD) simulations
    • Dry mole fractions to match traditional chemical engineering units
    • Cross-sectional area averages for boundary layer channnel flow reactor (CRESLAF) simulation results
    • Reaction rates of progress for all CHEMKIN Applications
    • Ability to view Internal Combustion Engine model results as a function of crank angle rather than traditional time unit

Highlights of What's New in CHEMKIN 3.7

PASR Application image

New Partially Stirred Reactor Application (PaSR) allows users to explore turbulent kinetic interactions by simulating both the mixing process and the detailed kinetics that may occur in combustion systems.

Reactor Network

New Reactor Network capability. Using the AURORA Application, users can now create reactor networks, including recycling of outflow streams to one or more reactors in the network, and multiple inlet streams. The reactor network can be run in both transient and steady-state.

New TWAFER and OVEND Applications. These two Applications simulate the heat transfer and chemical vapor deposition processes within batch furnaces for semiconductor processing of wafers in horizontal or vertical batch reactors.

Initialization and Restart from XML-based Solution Files. As a result of a new XML-based common data format, Application runs may now use the solution of any other Application to automatically provide initial conditions. For example, PLUG may start from an AURORA solution; CRESLAF may start from a PLUG solution. The Application User Interface allows selection of the XML file for either initialization or full restart using the new Restart button.

User Control of Units in Graphical Post-processor. The CHEMKIN Graphical Post-processor allows users to select the units used for the solution data before it is plotted, including both SI and cgs options.

More Powerful Graphical Post-processor. The CHEMKIN Graphical Post-processor will perform a variety of derived calculations at the user's request. These include: species rates of production, reaction heat production rates, alternate normalization of sensitivity data, linear deposition (or etch) rates, emissions indices for common pollutant species.

These are just the highlights. For more information on the new features and enhancements in CHEMKIN Release 3.7, see the CHEMKIN 3.7.1 Release Notes or request more information from Reaction Design.
