Mathis Bode (RWTH Aachen) - Multiphase flows: A numerical journey though automotive injection and combustion systems

Injection and combustion systems have to be re-designed and optimized for new e-fuels, and numerical simulations are essential in this process. E-fuels are chemical energy carriers made from renewable electricity and carbon dioxide. They can provide energy storage in a volatile renewable energy market and be used as clean and sustainable fuels for mobility and transport. The group of oxymethylene ethers (OMEx) has great potential in this regard. Different relevant aspects will be discussed in this presentation including simulations of nozzle internal flows and their effect on mixture formation, atomization, and ignition. Furthermore, data-driven approaches for sub-grid modeling are addressed.
