Increase your Turbocharger Performance

Turbocharging Simulation

Turbocharging allows automakers to reduce engine size and emissions while continuing to deliver the power and performance consumers demand. To improve overall engine performance, reduce pollutant formation, optimize NVH and ensure component durability you can simply combine our advanced simulation tools AVL BOOST™, AVL EXCITE™ and AVL FIRE™. They offer exactly what is needed to design advanced pressure charging systems.

Our offering includes:

  • Aerodynamically develop and optimize turbine and compressor wheels for highly efficient charging devices
  • Design new turbochargers with engine matching at every design step
  • Change compressor and turbine sizes and predict the effect of these changes
  • Ensure best NVH behavior and maximum durability

Optimize Rotor Dynamics
AVL EXCITE investigates the dynamic stability of the rotor bearing system. The multi-body dynamic solution includes non-linear models to detect critical speeds and analyze the influence of full or semi-floating bushing configurations.

Investigate and Minimize the Thermal Load
AVL FIRE offers a robust solution procedure for fast rotating systems. It predicts the thermal load of the turbine and compressor wheels as well as the turbocharger housing. FIRE solves simultaneously fluid and structure domains applying accurate near-wall flow and heat transfer models.

Pressure Wave Supercharger
In contrast to standard pressure-based charging devices, the pressure wave supercharger uses the kinetic energy of the exhaust gas directly to compress the fresh charge. AVL BOOST delivers highly predictive 1D modeling of the travelling shock and expansion waves.  No maps for mass-flow or efficiency characteristics are necessary.
