Biography

Pedro M. de Oliveira investigates fundamental problems of reacting, turbulent, and multiphase flows which underlie energy and fluid processes. In his PhD, he investigated how flames ignite and propagate accross a droplet medium, applying his experimental findings to the development of low-order ignition models for aviation gas turbines. Other applications of his research in the aerospace industry include use of alternative renewable fuels and development of laser-ignition devices. In 2020, his PhD work received the Clean Sky Academy PhD Award (European Comission) and the Sugden Award (Combustion Institute). His PhD thesis was also selected amongst the best fluid mechanics theses in the UK and Europe in the Osborne Reynolds Competition (1/3 finalists) and the da Vinci Competition (1/5 finalists). 

Pedro holds an MSc and an Engineering Degree in Mechanical Engineering (Federal University of Santa Catarina) and also carried out research at the Technical University of Munich. His master's research on two-phase flows in pipes received the Embraer-ABCM prize for the best master's thesis by the Brazilian Society of Mechanical Sciences and Engineering.
