Exhaust Aftertreatment

Flexible Kinetics Solution for Aftertreatment Devices

See the Exhaust Aftertreatment Brochure (PDF)

 

GT-POWER includes a built-in chemical kinetics and aftertreatment device library that
enables the user to model any AT device in isolation or together as an integrated system,
while providing the user the complete flexibility to modify or impose the kinetic
mechanisms participating in the conversion process. The design of this library is consistent
with our goal to provide a single tool for simulation of all aspects of engine/vehicle system. In
this respect, this library allows modeling of AT systems together with the vehicle, engine,
thermal management and the control system.
This tool is uniquely suitable for collaborative
development. The most important features of this library are as follows:
     • Highly intuitive input processor that uses existing GT-ISE graphical user interface
     • Single integrated tool (no 3rd-party tool is required)
     • Completely flexible in terms of specifying catalytic mechanisms
     • Allows modeling of all current catalysts and emission mitigating components
        (DPF, CDPF, SCR, LNT, DOC, AMOX, etc) as well as any new ones that are likely to be
        developed in the future
     • Built-in direct and DOE optimizers for parameter identification
     • Proprietary models can be encrypted by the user for distribution outside the organization
         to protect confidential data
     • Detailed thermal modeling of solid temperature distribution is enabled using GT-SUITE
         thermal component library

 

Efficient Solvers Compatible with RT Simulation

• Can be used as a standalone AT modeling tool as well as a part of an integrated
    system comprising of engine, vehicle and control sub-systems
• Relative positions and ordering of multiple AT components can be studied
• Varieties of solvers are provided for handling stiff DAE systems. The solution can utilize
    any of GTI's explicit, implicit, or quasi-steady numerical solvers to allow the user to
    make the choice between level of details vs. simulation runtime
• Complex integrated model can be virtually sectioned into separate circuits in order to
    achieve RT performance without sacrificing accuracy and coupling between the
    sub-systems
• Using built-in tools, AT models can be transformed into NN models to achieve high
    computational speed for RT applications
• Fast and efficient. The Quasi-steady (Q-S) solver is compatible with RT model
    requirement for standalone AT system simulation

 

• Quasi 2-D/3-D flow/heat transfer modeling to simulate
multi-D behavior of AT components
