The Leader in Engine CFD

AVL FIRE™

Thermo-Fluid Simulation Software

AVL FIRE™ is the leading CFD simulation tool in the field of combustion analysis. It specializes in the accurate prediction of all IC Engine relevant processes including injection nozzle flow, fuel injection, combustion, emission and exhaust gas aftertreatment. The software also supports the development of electrified powertrains and drivelines.

The Challenge

Engine Performance and Emissions

  • Which combustion concepts can I analyze?
  • How can I minimize engine-out emissions and tailor my aftertreatment system?
  • Can I optimize the intake and EGR Systems to meet performance, fuel consumption and emission targets?
  • Can I accurately predict flow, cavitation and erosion in low and high-pressure injection equipment?
  • Is it possible to link nozzle flow and fuel injection modelling?

 

E-Mobility Concepts

  • Is it possible to analyze the thermal behavior of E-drivetrain components?
  • How detailed can I investigate the electro-chemistry and electro-magnetics relevant for batteries and fuel cells such as SOFC, PEMFC, TEG, Li-ion and Li-Air batteries?

 

Thermal Load

  • Can I optimize residual stresses in structural parts resulting from heat treatment processes (e.g. cylinder head quenching) or from thermal load induced by heat release (e.g. combustion)?
  • Am I able to calculate the flow, pressure drop and heat transfer in components of the cooling circuit considering effects of nucleate boiling?
  • Can I use  the results to predict solid temperatures, thermal stresses and deformation due to thermal load?

The AVL Solution

The automatic pre-processor is able to efficiently generate grids for geometries with variable volume and/or featuring moving parts such as, pistons, valves, shafts, gears, etc. Automation shifts the otherwise significant effort required for generating a simulation model from the user to the computer.

 

The solver utilizes a pressure based segregated solution algorithm. It incorporates implicit time discretization as well as accurate conservative and bounded differencing schemes. High-end turbulence models allow for the precise description of transient effects within an engine or on a significantly larger scale.

 

The integrated postprocessor offers visualization and supports detailed analysis of results online during the simulation and offline interactively or based on marcros and scripts. In-build features allow the fast generation of charts, colored plots and animations in different formats to support the interpretation of both steady and transient phenomena.
