For the simulation of multi-physics, multi-scale phenomena, it is often advantageous to build
a comprehensive system-or process-model from a collection of sub-models, each of them …

Flame transfer function measurements of turbulent premixed flames are made in a model
lean-premixed, swirl-stabilized, gas turbine combustor. OH∗, CH∗, and CO 2∗ …

A study on the velocity sensitivity and intrinsic thermoacoustic stability of a laminar,
premixed, Bunsen-type flame is carried out. Direct numerical simulation (DNS) of the flame …

This paper deals with the response of swirling flames submitted to acoustic velocity
disturbances when the rotation of the flow is produced by an axial or a radial swirler. The …

The effects of hydrogen addition on the flame dynamics of a bluff-body stabilized methane–
hydrogen turbulent flame are studied with large eddy simulation (LES). The LES is carried …
