AVL FIRE™ Modules

Physics and chemistry available with AVL FIRE™.


AVL Approach

AVL FIRE™ offers solving of the most advanced fluid-flow problems easily, fast and with the highest accuracy. To account for relevant physics and chemistry, AVL FIRE™ provides a comprehensive set of models which are modularly arranged, enabling its users to execute a large number of simulation tasks related to the development and optimization of fluid flow guiding components efficiently and effectively.


Benefits at a Glance

AVL FIRE™ offers:

  • Scalable solutions: from empirical models to complex once most accurately reflecting reality
  • Continously developed and extensively validated
  • Proven applicability due to integration in AVL's in-house development and service projects

Aftertreatment Module

The AVL FIRE™ Aftertreatment Module is part of the AVL Aftertreatment Suite, which consists of AVL BOOST™, AVL CRUISE™ and AVL FIRE™. It comprises the most advanced and powerful set of capabilities for emission treatment simulation on the market. Due to its outstanding performance in terms of physical and chemical modeling the module has become an indispensable element in the design, development and optimization of aftertreatment devices for internal combustion engines and industrial exhaust gas cleaning.


Combustion and Emission Module

The AVL FIRE™ Combustion and Emission Module enables the calculation of species transport and mixing phenomena and the simulation of ignition, combustion and emission formation in internal combustion engines and other technical combustion devices under premixed, partially premixed and/or non-premixed conditions.


Electrification Module

The AVL FIRE™ Electrification Module offers seemless coupled multi-phase fluid flow, chemistry, electric field and heat conduction simulation supporting the development of batteries, fuel cells, thermo-electric generators and electric motors.


Eulerian Multiphase Module

The AVL FIRE™ Eulerian Multiphase Module is used to simulate flows potentially consisting of an arbitrary number of fluids and/or phases. Its major feature is its ability to calculate for each phase the volume fraction distribution in addition to all other flow variables.


Lagrangian Multiphase Module

The development of AVL FIRE™ has a strong focus on capabilities related to the simulation of dispersed sprays, in particular - but not exclusively - such as those occurring in internal combustion engines during the injection of liquid fuel. The Lagrangian Multiphase Module used in that context accounts for droplet primary and secondary break-up, turbulence dispersion, collision and coalescence, distortion and drag, evaporation as well as droplet/wall interaction.
