PhD project:
Title: Experimental characterization of ignition events in CVC like conditions, WP2
To experimentally investigate the different phenomena involved in the ignition stage in a CVC application. For this purpose, a lab-scale facility will be used to allow for the separation of the various contributions as much as possible. The setup will allow a well-controlled flow, with the possibility to vary the mean velocity and turbulent scale. Both energy and power effects of the ignition system on the ignition process will be studied. Starting from propane/air gas mixtures, the effect of heavier fuels, representative of kerosene, and hydrogen can be analysed. Finally, the effect of dilution by synthetic, cold-burned gas will also be investigated. The activity will take advantage by the direct exchange of information with ESR7, who works on a similar topic for the RDC technology.
Supervisors: Prof. Julien Sotton, Prof. Marc Bellenoue and Prof. Camille Strozzi
Mentor: Prof. Myles Bohon
Planned secondments:
3 months at TUB (M11-M13) to compare the two different PGC technologies in terms of ignition, 3 months at UC to compare ignition process on different combustor geometry (M26-M28)
Background:
My degree in Mechanical Engineering at the Pontifical Catholic University of Rio de Janeiro was completed in January 2019. During the course, I participated in the Baja team for two years. I carried out my Mechanical Engineering Graduation supervised by Prof. Luís Fernando Figueira da Silva and Dr. Fernando de Souza Costa, from the National Institute for Space Research (INPE – Brazil). The study has characterized the instabilities in solid propellant rocket engines, thus expanding the contents covered in the disciplines of the undergraduate course. I started my research activities with a master’s degree in mechanical engineering at PUC-Rio in August 2019. My research deals with the experimental study of the flame flashback process in hydrocarbons (methane or propane) diluted by CO2 and air. The correct description and prediction of the situations in which the flame flashback may occur is of crucial importance for the safety of several industrial processes, in particular those of the oil and gas industry. With a full scholarship from FM Global, I presented the preliminary results at the 1st Asia-Pacific Combustion Institute Summer School (Chile, 2019), where I obtained the second-place award for a poster presentation. I also won a full scholarship and presented this work at the KAUST Research Conference: Transition to Low Carbon Mobility (Saudi Arabia, 2020). The results obtained also led to the writing of an article “Determination of the CO2 and N2 dilution influence on flame flashback limits of methane and propane combustible mixtures” published at ENCIT 2020 (18th Brazilian Congress of Thermal Sciences and Engineering).
