Researcher

My main areas of interest and experience are combustion, flames and explosions of gaseous homogeneous systems, focused on: (a) explosion initiation, propagation and quenching in enclosures at various initial conditions; (b) flammability of hydrocarbon-air mixtures, in the presence of diluent and/or inhibitor gaseous additives; (c) chemical kinetics in homogeneous systems. Within these directions, I studied mainly the evolution of explosions processes in closed vessels, an important domain regarding safety in all fields in which flammable compounds are involved. All the topics approached so far aimed to report new data on characteristic properties of flammable mixtures, as well as a better knowledge of this complex field. During my research career, I was a director or a team member of several national projects. As a sign of appreciation of my research activity, I received the Nicolae Teclu Romanian Academy Award in 2014.

Abstract:

The main objective of this project is the investigation of hydrogen influence on gas-phase combustion of hydrocarbons in air, in deflagration regime, by experimental and numerical methods. Under the project, relevant initiation parameters (the quenching distance and the minimum ignition energy) and propagation parameters (normal burning velocity and propagation speed) will be examined, in correlation with the initial composition and pressure of flammable mixtures and with characteristic flame properties (adiabatic flame temperature, total concentration of active radical species).

The study will be realized with LPG (Liquefied Petroleum Gas)-air mixtures with added H2, at various initial LPG concentrations within its flammability limits, hydrogen fractions (5-30 vol%) and initial pressures, within 0.5 and 2.0 bar, at ambient initial temperature. LPG has the typical composition of Romanian blends.

The estimated scientific results delivered by the project consist in the full characterization of LPG-air-H2 mixtures from point of view of flammability parameters, in order to obtain safety operating characteristics for storage, transport and manipulation of such mixtures and to develop increased energetic efficiency with low pollutant emissions.

Abstract:

The project seeks to promote young researchers or future researchers that are eager to improve the quality of life by creating and testing out new non-toxic alloys with antibacterial properties. Through theoretical modelling and utilizing modern casting techniques we will obtain an alloy that has superior properties and lower costs than existing ones and that can be used for orthopedic and dental implants alike. The alloy is to be subjected to specific electrochemichal and corrosion tests and also in-vitro cell growth tests. Surface analysis wil be made using modern techniques such as SEM, XPS and AFM.

Abstract:

The main objective of this research is the examination of deflagration propagation in gaseous fuel-air and fuel-air-inert mixtures with the scope to map the flammability range of fuel in air in the presence of various inert additives. The project will be realized by an experimental and a computational study of fuel-air explosions in the vicinity of flammability limits, in confined conditions. Ethylene is chosen a representative fuel. The objectives of the project are: (1) the experimental determination of explosion limits of ethylene-air and ethylene-air-inert mixtures, at ambient initial conditions. Nitrogen, argon or carbon dioxide will be used as inert gases. (2) calculation of LOC (limiting oxygen concentration) for ethylene-air-inert mixtures using an original method based on the correlation between adiabatic flame temperature at LOC and adiabatic flame temperature at the lower explosion limit; (3) development of a new method to predict LOC based on examination of normal burning velocities of fuel-oxidizer limit-mixtures and of fuel-oxidizer-inert mixtures at the apex of the flammability range. The new method uses the concept of threshold value of the normal burning velocities for gaseous systems at the lower explosion limit and at the apex of the flammability range. The flammability limits are essential safety parameters in industry or domestic fields. Inerting a fuel-air mixture is also a method to limit the pollutant emissions generated by the combustion process.
