The Importance of Simulation when Talking about E-fuels and Biofuels

News from AVL’s Virtual ICE Development

The introduction of e-fuels and biofuels is a promising option to help tackle CO2 emission problems. AVL’s simulation tools are here to help you overcome many of the related challenges.

Thermodynamic cycle simulation and 3D In-cylinder flow analysis support required design adaptions. A numerical optimization step is necessary to achieve the hard development targets in regard to pollutants and CO2, while at the same time keeping an eye on performance, efficiency, durability and costs.

However, there are challenges. For example, pressure and temperature dependent fuel properties have to be accessible and accounted for. The fuel composition has a significant impact on the air/fuel mixing as well as on the wall interaction effects. Simulating combustion requires a detailed knowledge about the right ignition delays and flame speeds. To predict heat release, wall heat transfer and emission formation, solving a whole set of chemical reactions is required.

The good news is that you can do all of this using AVL’s simulation solution because we have upgraded our tools to handle fuels extremely flexibly. Fuels may be defined as single or multi-component fluids and the software fully accounts for the properties and effects of the individual ingredients.

This allows you to go into detail when simulating conventional fossil-resource based fuels and, even more importantly for future concepts, it enables engineers to investigate new green fuels or different blends of fuels. It is these capabilities that qualify our tools AVL CRUISETM and AVL FIRETM M to play a key role in the development of clean e-fuels and bio-fuel applications.
