Title | Numerical study of ammonia explosion characteristics |
Category | PhD Studentship |
Employer | University of Surrey |
Location | United Kingdom |
International | No, only national applications will be considered |
Closure Date | Friday, January 31, 2025 |
Description: |
The Internal Energy Agency (IEA) considers ammonia (NH3) key to decarbonising
shipping. A new report from the IEA believes it will be ammonia, not methanol,
that must play a major role if shipping is to meet its ambitious emissions
reductions targets. While the technical issues related to the combustion of
ammonia in engines have already attracted considerable attention from the
international combustion community. No study in the public domain addressed
accidental combustion of potential leaks of NH3 in engine rooms, which are
confined/semi-confined. Potential ignition, the resulting fire and explosion
risk as mitigation measures such as venting should be considered to inform
regulations and policy as well as the development of mitigation measures, such
as venting.
The PhD project aims to address the above issues with specific focus on
vented explosion mitigation. The specific tasks include:
• Analyse the combustion characteristics of ammonia in the context of fire
and explosion safety.
• Establish a strategy to extend HyFOAM, the in-house modified
computational fluid dynamics (CFD) code for modelling hydrogen explosions
developed within the frame of OpenFOAM, to ammonia explosions. The modified code
will be named as NH3FOAM.
• Validate the predictions with published experimental data of similar
fuels and/or any new data on ammonia explosions which may come out during the
PhD.
• Conduct a series of CFD predictions to examine the effects of different
venting strategies, considering the geometric layout and environment in the
propulsion systems and engine room.Use the predictions to extend the engineering
model for vented hydrogen explosions previously developed in the HySEA
(Improving Hydrogen Safety for Energy Applications (HySEA) through pre-normative
research on vented deflagrations) project to ammonia.
The studentship cover Full UK tuition fees and Stipend at UKRI rates (Full time annualised £18,622)for
3.5 years. Because of the huge difference in tuition fees between UK and international rates (including
EU), the advert is only open to British Students. Further information about tuition fees can be found at
