  This thesis is devoted to the numerical investigation of premixed Flames subject to intrinsic hydrodynamic instabilities as well as turbulence. Laminar as well as turbulent premixed combustion can be largely influenced by the onset of hydrodynamic instabilities which can cause a significant increase in flame corrugation and, as a result, in the turbulent flame speed, especially when low turbulence intensity level are present. Indeed, such instability is responsible for the formation of sharp folds and creases in the flame front and for the wrinkling observed, undergo certain conditions, over the surface of expanding flames. Hydrodynamic instability is a result of thermal expansion across the flame and its role is particularly dominant in large-scale flames, when flames are constrained by domains larger than several hundred times the flame thickness. The understanding of these phenomena and their interaction with turbulence can play a potentially significant role in practical combustion systems such as gas turbines and, more generally, in industrial and domestic burners. The aim of this thesis is to develop a numerical tool capable of simulating the propagation of turbulent premixed flames under the influence hydrodynamic instabilities and gather qualitative and quantitative data on flame properties such as morphology and global propagation.

  This collaboration with RWTH university is focalized on the interplay of the flame instability with a turbulent field for different pressure values, aiming to characterize all of the main features of turbulent premixed flame propagation whenever, under equivalent laminar flow, the operative conditions would favor the onset of instabilities. Since the DL instabilities play an important role in premixed turbulent combustion, as control the growth of unburned mixture fingers and therefore cause oscillations of the flame surface area, turbulent burning velocity, and mean flame brush thickness. A clear identification of a regime where the turbulence dominate over the large scale effects still need to be assessed, and in order to do so, larger DNS database are necessary. In the present project, in order to study the effects of pressure on the flame, a systematic analysis of the hydrodynamic instability length scales of methane-air premixed flames is presented. Their research activities span from the study of turbulent chemistry interactions, pollutant formation, development and reduction of reaction mechanisms, simulation of industrial and household burners as well as gas turbine combustion.
