What is DARS? |
You can access DARS in three different ways, depending on your requirements:
DARS Basic:
Provides easy access to complex chemical models. These include
a wide range of 0D reactor models and 1D flame calculations. You can read
and visualize existing reaction mechanisms (including CHEMKIN (trademark) format);
perform sensitivity, flow and lifetime analyzes; and reduce thousands of reaction
mechanisms down the vital few, with DARS’s reduction module.
DARS LGT:
The library generation tool can produce libraries using a reactor
tool for a combustion model in the CFD or ESM computations. One such example
is the generation of the stationary or transient flamelet libraries for
a flamelet model in a CFD code. The generation of flamelet libraries
is very fast and robust and has been tested for various complex chemistry
models. An ignition library can also be generated for different equivalence
ratios for a given fuel and air mixtures. This information can be
used in a CFD or a lower dimensional computations to track ignition delays.
In short, this library generation tool gives you a capability to
combine turbulent interactions with complex chemistry for the turbulent
reacting flow simulations.
DARS ESM:
The Engine Simulation Module provides additional functionality
specifically tailored to engine simulations. This includes coupling
to leading 1D codes, such as GT-Power, as well as specialized homogeneous
reactor models for HCCI, SI engines and catalysts and Stochastic reactor
models for HCCI, SI and CI engines. Enhance your 1D simulations with
accurate representation of complex chemistry.
DARS CFD:
Provides robust and optimal complex chemistry for CFD. Detailed
gas-phase and surface chemistry can be modeled. Significant savings
in calculation time can be achieved through reaction reduction either performed
a priori or on the fly, and DARS uses solution-mapping methods (such as
DOLFA). Its flamelet libraries include turbulence interaction and
soot, make it a must for combustion calculations.
