3. Conclusion

The numerical simulation of aeronautical combustion chambers requires models for turbulent, reactive, and most often two-phase flows. The increasingly widespread use of LES for solving this type of problem has enabled numerical tools to become predictive for many issues, unlike stationary methods such as RANS. It should be noted, however, that unsteady LES methods remain costly, and it is hoped that a computational strategy will one day emerge that is intermediate between RANS and LES, which would make it possible to predict the main characteristics of the flow at a lower cost.

Significant progress has also been made in taking detailed chemistry into account, whether through the use of tabulation methods or the so-called analytical reduction of reaction mechanisms. In order to go even further, some laboratories are currently working on methods known as "virtual...
