Lagrangian filtered density function modeling of a turbulent stratified flame combined with flamelet approach

This work aims to show the advantage of the Lagrangian transported FDF and the hybrid approach for a highly stratified flame, one of the most challenging members of the well-known Cambridge stratified flame series. Different criteria are tested for triggering the switch-over between the methods to maximize the efficiency of the hybrid approach, where basic flame quantities such as mixture fraction were predicted well with the assumed FDF model, and the temperature and mass fraction of carbon monoxide were predicted better by the hybrid method, featuring the transported FDF technique.”

Diese Arbeit zielt darauf ab, den Vorteil des Lagrangeschen transportierten FDF und des hybriden Ansatzes für eine stark geschichtete Flamme zu zeigen, einem der anspruchsvollsten Mitglieder der bekannten geschichteten Flammenserie von Cambridge. Es werden verschiedene Kriterien für das Umschalten zwischen den Methoden getestet, um die Effizienz des hybriden Ansatzes zu maximieren.
