Modelling of Spray Droplets in a Liquid Fuel/Air Mixture Using a Sharp Cartesian Method

Improving engine performance, including fuel economy, emissions, and power output, is a very complex issue and still requires further research. Since transportation systems, and specially aircrafts, are typically powered by liquid fuels, the process of fuel/air mixture preparation plays a key role in combustion (i.e., fuel burning). Nonetheless, since fluid properties such as density and viscosity vary by several orders of magnitude across fluid/gas interfaces, accurate modelling are possible only with careful treatment of all important phenomena including large density jumps across fluid interfaces. Therefore, to accurately capture the gas-liquid two-way effects, utilizing an interface tracking method such as the Cartesian method, which has been developed by MEMPHIS group at Inria Research Center, is essential. Utilizing this method, a reliable model for the breakup of droplets will be proposed, which will lead to develop new liquid fuel/air preparation techniques and hence the possibility for more efficient and less pollutant combustion technologies.
