Hydrogen vehicles are being deployed as a part of the deep decarbonisation strategy nationally and internationally. These vehicles are expected to provide the same or better level of safety compared to fossil fuel vehicles. Use of gaseous hydrogen stored in composite pressure vessels at nominal working pressures 700 bar is the main solution for onboard hydrogen storage for light- and heavy-duty transport applications. Fire resistance rating (FRR) of modern composite tanks is about 4-6 minutes in gasoline fire. This low FRR makes rupture of such tanks a major safety concern in a case of thermally activated pressure relief device (TPRD) failure. Blast wave and fireball following a high-pressure tank rupture in a fire represent serious pressure and thermal hazards threatening life and property losses.
Analysis of experimental data shows that a car deformation by the blast and its displacement from original location:
(1) expends significant fraction of mechanical energy of compressed hydrogen released instantaneously during tank rupture,
(2) presence of car over the tank intensifies hydrogen combustion and thus affects fireball dynamics due to higher turbulisation and mixing of released hydrogen under the vehicles. Thus, hazards analysis methods developed for the open atmosphere tank rupture, including Computational Fluid Dynamics (CFD) models, are not perfectly applicable to assess hazards of onboard storage in real scenarios.
Accounting for vehicle deformation and displacement is essential to realistically predict pressure and thermal loads on humans and structures. This is typically done by using Finite Element Methods (FEM).
The project aims to develop a coupled CFD-FEM model applicable to analysis of realistic pressure and thermal loads after onboard tank rupture in a fire in a wide range of scenarios for variety of tank volumes, storage pressure, mounting position on a vehicle; vehicle location (open atmosphere, workshop, tunnel, etc.). ANSYS family of Fluid and Structure computational tools will be used as a platform for model development. Experimental data available in the literature and to be obtained in ongoing H2020 (FCH 2 JU) HyTunnel-CS project, coordinated by Ulster University will be used for the model validation. Outcomes of this project will inform regulators, OEMs, health and safety authorities, fire and rescue services about realistic hazards of potential fire accidents with hydrogen vehicles. The research results will feed development of engineering methodology to assess blast wave overpressure and fireball size in the event of catastrophic tank rupture and development of appropriate prevention and mitigation strategies.

The Doctoral College at Ulster University
I had an interesting time at Ulster University, Jordanstown. Many thanks to all the lecturers, library staff and research school for their time and effort getting me through my PhD!
Philip Bradley - PhD in Architecture, Built Environment and Planning
My proudest moment was when I was accepted to pursue my PhD in Ulster University. My favourite memory was how I met my group of friends who also pursue their dreams in this foreign country. I'll never forget the tough times I underwent during my study, but thanks to those times that I finally managed to lose weight. I couldn't have got through this without my supervisors' support, kind encouragement and firmest trust. If I could speak to myself at the start of my PhD, the best piece of advice I would give myself would be - do not procrastinate, you gotta learn to move forward in life when you feel stuck.
Mengmeng Dou - PhD in Architecture, Built Environment and Planning
I came to Ulster University to challenge myself with a PhD study under Vice-Chancellor's Research Studentship at the Centre for Sustainable Technologies in Architecture, Built Environment and Planning. My supervisors helped me much from giving valuable guidance to supporting any difficulties, which makes me feel that I am the luckiest student.I would like to take this opportunity to thank my supervisors, family, friends and colleagues for supporting me tirelessly. Without you, I couldn't have got through my PhD with some great achievements:Best PhD Research Paper in Architecture, Built Environment and Planning, Ulster UniversityBest Student Paper Award at the conference of World Congress on Engineering and Computer Science 2017, San Francisco, USA.Student Registration Grant for demonstrating academic excellence in research at 17th International Conference on Sustainable Technologies (SET 2018), China.
Khoa Xuan Le - PhD in Architecture, Built Environment and Planning
I worked for 35 years for the Housing Executive - latterly as its Head of Research. I had completed an MSc in Urban Policy in the 2000s - and it had been a longstanding ambition of mine to complete a PhD that brought together a number of strands of policy-related research that had been of particular interest to me. Undertaking a PhD at Ulster University allowed me to fulfil this ambition in an enjoyable manner.Completing my PhD has brought me an immense amount of personal satisfaction. A major part of this was down to the incredible support I received from my two supervisors Professor Stanley McGreal and Dr Michael McCord. Their ongoing advice, encouragement and support helped take me outside my comfort zone and played a major part in my achievement. Even my viva proved to be an enjoyable experience and enabled me to feel that I had gained a level of expertise in a sphere that could make a small but significant contribution to addressing some of the key housing issues facing policy
Joe Frey - PhD in Architecture, Built Environment and Planning
I am a senior researcher at Korea Fire Institute which is a state-owned company specialised at fire safety engineering in the Republic of Korea. I obtained BSc and MSc in mechanical engineering. Prior to enter a PhD course at the School of the Built Environment in Ulster University, I worked for over a decade in the engineering industry. With relation to my PhD topic, my current research field is on fire safety using experimental and numerical approaches.Finally, I finished my study in Ulster University and became a Doctor of Philosophy in a field of fire safety!! There were a lot of good memories at Ulster University. I will never forget the rainbow on the Jordanstown campus which helps me to relieve my stress caused by stuck in concrete damaged plasticity theory. I felt great when receiving an annual PhD conference award as the best poster. I was excited to spent time with my officemates, Rumeel, and Emmanuel. I love every moment at Room 4B01 because it was a time to enhance my

Benjamin Fumey - PhD in Architecture, Built Environment and Planning
I studied my Integrated Masters (MSci) at Jordanstown from 2008-2012. After a few years working as an Estate Agent, I went back to academia to complete my PhD, looking at the broad area of health within the field of planning.Many PhDs are given a topic to begin with, however when I applied for the PhD scholarship I had to create my own research topic. This took me a while to establish, but eventually my hard work paid off and I narrowed my research into an area I am truly proud of - Active living, how the built environment can influence physical activity and how this was interpreted in the domains listed in my thesis title. My favourite aspect of the PhD was presenting my research and getting the acknowledgment from other academics that my research was interesting, robust and well thought out. I submitted an abstract to AESOP, an annual planning conference, and was given the opportunity to present my work in Venice. I also presented my work to the president of RTPI. There is nothing
