WebFeb 14, 2024 · Recent advances in the application of computational fluid dynamics (CFD) for turbulent combustion with the relevance for gas turbine jet engines are discussed. Large eddy simulation (LES) has emerged as a powerful approach to handle the highly turbulent, unsteady and thermochemically non-linear flows in the practical combustors, and it is a … WebApplications of PDF and FDF methods to premixed turbulent combustion are more complicated than calculations of non-premixed turbulent combustion. The appearance of fast flamelet chemistry may result in very thin reaction zones such that scalar mixing can take place on scales which are much smaller than all scales of turbulent motions [2, 29 ...
