Biography

Dr Neville Rebelo is a researcher in cryogenics, thermofluids, and heat transfer, with extensive experience in the design, operation, and analysis of advanced cooling and energy systems for aerospace and sustainable technologies. He holds a PhD in Thermofluids from Loughborough University, where he developed and validated an experimental facility to study liquid nitrogen evaporation using optical diagnostics, in collaboration with the Dearman Engine Company on zero-emission energy systems.

Prior to his doctoral studies, Dr Rebelo worked as a Cryogenic Project Engineer at Inox CVA, contributing to large-scale projects with the Indian Space Research Organisation (ISRO) and ITER-India, including the design of helium cryolines for the world's first fusion reactor. His work on modelling cooldown performance for liquid oxygen (LOx) tanks directly supported ISRO's space programme.

Dr Rebelo is currently a Researcher in the Power Electronics and Machines Research Institute (PEMRI) at the 海角黑料, where he is developing advanced cryogenic cooling solutions for next-generation clean aviation propulsion systems. Since joining the University in 2020, he has led and delivered multiple projects investigating multiphase flow and heat transfer in transmission systems using advanced optical techniques. His research spans cryogenic cooling, hydrogen thermodynamics, and energy-efficient thermal management for hydrogen-electric propulsion technologies.

A Chartered Engineer (CEng) with the IMechE, Dr Rebelo actively contributes to the research community through mentoring and outreach as a committee member of the Engineering Research Futures (ERF) network. His long-term goal is to advance the understanding and practical implementation of liquid hydrogen thermal management systems to enable safe, efficient, and sustainable aviation.
