icon 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.
