Research interests

My research interests are centered in the area of combustion and energy, and I am particularly interested in the application of CFD simulation in flameless and micro-scale combustion systems. During my Masters in UTM, I joined the High Speed Reacting Flow laboratory (HiREF) to develop a 3D turbulence model of their lab-scale flameless combustor feed by complex fuel (biogas). We found out that biogas as a source of renewable energy is faced with problems in conventional combustions because of its low calorific value (LCV); however, such biogas could be an excellent source of energy for flameless combustion systems. My master thesis focused on effects of bluff body shape on the flame stability in premixed micro-combustion. In this study, the blow-off limit of nine different bluff bodies and combustion efficiency of micro-combustor were examined and a new bluff body called “wall-blade” was introduced, that greatly enhanced emitter efficiency.

Recently, considerable attention has been paid to natural gas, because it burns more cleanly than other hydrocarbon fuels, such as oil and coal, and produces less carbon dioxide per unit of energy released. My current research project is devoted to improving a detailed kinetic mechanism for combustion and oxidation of natural gas. The kinetic characterization of natural gas combustion represents an important and crucial role to analyze and describe, in order to correctly predict the flame characteristics and stability. Therefore the aim of this study is to propose a detailed kinetic mechanism with predictive capabilities in a wide range of operating conditions (conventional and flameless modes), describing the oxidation and combustion of natural gas.

Project title: Detailed kinetic mechanisms for combustion and oxidation of natural gas

Objectives. The kinetic characterization of natural gas combustion represents an important and crucial point to analyze and describe, in order to correctly predict the flame characteristics and stability. Thus, the main objective of this project is the improvement and tuning of a detailed kinetic mechanism with predictive capabilities in a wide range of operating conditions, describing the oxidation and combustion of natural gas. New recent data have appeared in the literature with new and well validated estimation of rate constants for many elemental reactions of the natural gas oxidation. The thermodynamic properties of species and radicals are now evaluated with a very high accuracy. All this information will be introduced in an existing mechanism to improve the performances. The quality of the resulting detailed kinetic scheme will be constantly measured through the comparison with experimental data available in the scientific literature and/or data available from the CLEAN-Gas project. At this purpose a database will be developed and automatic comparisons with statistical analyses will be proposed.

Expected results. Detailed kinetic mechanisms for natural gas combustion and oxidation validated very wide ranges of operative conditions.

Planned secondment.BE-ULB (8-10 months): Chemical kinetic mechanism uncertainty quantification in combustion problems, including reactors and laminar flames. The primary objectives is to determine which reactions contribute most to the uncertainty in the predictions and whose rates may require further refinement.
