The paper examines the combined effects of several interacting thermo-acoustic and
hydrodynamic instability mechanisms that are known to influence self-excited combustion …

The paper presents the numerical studies on spark ignition in a turbulent mixing layer
formed between a fuel stream (H 2/N 2) and air flowing in the opposite directions. Compared …

This paper presents an analysis of numerical and modelling issues based on a simulation of
nitrogen-diluted hydrogen lifted flame evolving in a hot co-flow. We apply the large-eddy …

We investigate the dynamics of counter-current reacting flow under varying strengths of the
counterflow and report the occurrence of global instability phenomena. This clarifies the role …

In this paper, we investigate the flow and flame dynamics within a combustion chamber
supplied with nitrogen-diluted hydrogen fuel and air as oxidiser. The chamber is equipped …

Temporal evolution of an ignition kernel in a spark ignited turbulent hydrogen–air mixing
layer is studied using the large eddy simulation approach with an implicit treatment of the …

In this study, we employ the potential of the global instability phenomenon to qualitatively
alter the dynamics of a turbulent flame. We adopt the large eddy simulation method and an …

The aim of the research is to analyze the accuracy of the approximate deconvolution method
(ADM) for large eddy simulation (LES) modelling of auto-ignition and flame propagation in a …

This thesis describes one of the first computational works to investigate the physical
feedback mechanisms associated with self-excited, combustion-driven instabilities in gas …

In the current work, the jet spray flame reflecting an experimental configuration of a piloted
spray burner with a vitiated hot co-flow is modeled using large eddy simulation (LES). We …
