Main research interests

Dr Ivan Langella obtained his MS degree in aerospace engineering from the University of Naples Federico II, Italy, in 2011 and his PhD in engineering from Cambridge University in 2015 after a period spent as experimentalist research assistant at the University of Yale, USA. He has then worked as a research associate in combustion engineering at the University of Cambridge before moving to Loughborough University as Lecturer in 2018. He is also an external collaborator with the University of Cambridge and is active in enterprise development as director of a research based startup.

His research is in the broad area of thermo fluid science and computational modelling, with specific focus on turbulent reacting flows, in particular the fundamental physics of lean premixed combustion and its application to practical devices like industrial and aero gas turbines. This involves performing analyses to identify ways to improve efficiency and reduce emissions in such devices using various modelling strategies for high-fidelity simulations. This work also includes the study of thermo-acoustic instabilities, the coupling between rate of heat release and pressure fluctuations in practical energy producing devices, where the aim is to reduce these instabilities and thereby the sound emission to increase the overall performance of the engine.

Additional projects and collaborations are in the study of the fundamental physics and application of numerical methods to fluid-structure interaction problems for energy production devices (gas and wind turbines, scramjets and nuclear reactors) and bio- & micro-fluids. Some of the projects above are inter-disciplinary and/or involve close collaborations with other groups, institutions and industries.
