PhD Position in Modelling of Accident Scenarios from Liquid Hydrogen Transport and Use


NTNU - Department of Mechanical and Industrial Engineering


Trondheim (Norway)


The Faculty of Engineering Science ( at the Norwegian University of Science and Technology (NTNU) has a vacancy for one PhD candidate position at the Department of Mechanical and Industrial Engineering (

Information about the department

The PhD candidate will be affiliated with the Department of Mechanical and Industrial Engineering (MTP), RAMS (Reliability, Availability, Maintenance, and Safety) group ( The overall mission of the RAMS group is to contribute to safer, more productive and more sustainable industry, transport and society.

This PhD is part of the SH2IFT project on “Safe Hydrogen Fuel Handling and Use for Efficient Implementation”, funded by the Norwegian Research Council (ENERGIX-programme) and involving internationally renowned research institutes. The PhD candidate will work in collaboration with SINTEF, RISE Fire Research and Gexcon.

Work description

Hydrogen is not necessarily less safe than other fuels, provided it is handled according to its unique properties. However, there is still critical lack of knowledge on accident scenarios involving this substance. For instance, loss of containment of liquid hydrogen due to possible vessel damages may lead to a series of accident scenarios, such as Rapid Phase Transition (RPT) or boiling liquid expanding vapor explosion (BLEVE). Currently available models for these events were developed and validated for substances with properties that are different from hydrogen.

The PhD candidate will be responsible of developing and validating thermodynamic and mechanical models for simulation of accident scenarios from liquid hydrogen transport and use. In particular, the RPT and BLEVE development and effect in terms of blast waves will be studied. For this activity, the candidate will have the chance to participate to and use data from experimental tests on H2 fire and explosions, conducted within the SH2IFT project.

The position is awarded for a period of 3 years.


A master's degree with an average grade B or better as measured in ECTS (European Credit Transfer System) grades, or an education at the equivalent level is required. Masters in Chemical Engineering, Mechanical Engineering, Physics, and related degrees are welcome. We expect the candidate to be able to show modeling skills and a research-oriented master thesis within one of the areas mentioned.

Applicants must provide evidence of good English language skills, written and spoken. The following tests can be used as such documentation: TOEFL, IELTS or Cambridge Certificate in Advanced English (CAE) or Cambridge Certificate of Proficiency in English (CPE). Minimum scores are:

•TOEFL: 600 (paper-based test), 92 (Internet-based test),

•IELTS: 6.5, with no section lower than 5.5 (only Academic IELTS test accepted),

•CAE/CPE: grade B or A.

In extraordinary circumstances, formal documentation of language skills can be relinquished. In such cases, the candidate’s language skills will be assessed in a personal interview.

Conditions of appointment

PhD Candidates are remunerated in code 1017, and are normally remunerated with a gross salary NOK 436 900 before tax deduction. There will be a 2 % deduction to the Norwegian Public Service Pension Fund from gross wage. As a member of the Norwegian Public Service Pension Fund you are offered:

•A good pension scheme
•A favorable housing loan interest
•Good insurance schemes

Applicants for a PhD will have to engage in an organized PhD training program, and appointment in the positions requires approval of the applicants plan and qualifications for the PhD study within three months from the date of commencement of the PhD position. See and for more information.

The engagement is to be made in accordance with the regulations in force concerning State Employees and Civil Servants. The positions adhere to the Norwegian Government's policy of balanced ethnicity, age and gender. Persons with immigrant background are encouraged to apply. NTNU´s objective is to increase the number of females in scientific positions and female applicants are therefore encouraged to apply.

The position is financed for 3 years. Place of work is at NTNU in Trondheim.
