Biography

Pedro M. de Oliveira investigates fundamental problems of reacting, turbulent, and multiphase flows which underlie energy and fluid processes. His research on clean propulsion probes the physics of transient phenomena and emissions of hydrogen, SAFs and kerosene flames, based on the development and application of laser diagnostics to canonical and realistic flows. He has worked on novel combustor concepts, numerical tools, and experimental methods for multiphase flows. Applications of his research in the aerospace industry include, for example, models for predicting the ignition behaviour of gas-turbines, certification of new alternative renewable fuels, and development of novel laser-based ignition devices. 

Recently, he has been elected an Emerging Leader – one of the best early-career researchers (<10y since PhD) in measurement and metrology – by the journal Measurement Science and Technology. Additionally, his PhD work on ignition and propagation mechanisms of spray flames has received the following distinctions:

  • da Vinci Medal 2020, for the best PhD thesis in fluid mechanics in Europe, awarded by the European Community for Research in Flow, Turbulence and Combustion;
  • Clean Sky Academy Best PhD Award 2020, for outstanding research work in applied sciences and engineering for aeronautics, awarded by the Clean Sky Joint Undertaking (European Commission);
  • Sugden Award 2020, for the paper with the most significant contribution to combustion research by a UK researcher, awarded by the Combustion Institute (UK);
  • Osborne Reynolds Competition in 2020, amongst the 3 best works in fluid mechanics (UK).

Pedro holds a Masters and an Engineering Degree in Mechanical Engineering by the Federal University of Santa Catarina. His masters research on two-phase flows in pipes received the Embraer-ABCM Prize for the Best Masters Thesis (2014, Brazil) by the Brazilian Society of Mechanical Sciences and Engineering.
