Doctoral student in Computational Fluid Dynamics for Hydrogen Engines

Description of the workplace

Lund University's Department of Energy Sciences is a leading center for research in energy, fluid mechanics, and sustainability.

The Division of Fluid Mechanics at Lund University's Department of Energy Sciences is a distinguished and dynamic research environment, recognized for its cutting-edge contributions to the field of fluid mechanics, particularly in the areas of energy systems and sustainable technologies. Our division prides itself on a collaborative and innovative research culture, where interdisciplinary approaches are actively pursued.

At our division, you will find a diverse team of experts specializing in various aspects of fluid dynamics, heat transfer, and multi-physics problems, all working towards developing sustainable solutions for contemporary challenges. Our facilities are equipped with state-of-the-art computational resources, enabling advanced simulations and modelling. Moreover, we actively engage in collaborations with other leading experts on laser diagnostics, automatic control, heat transfer and life cycle assessment, both nationally and internationally, promoting a network of expertise and innovation.

This position offers a unique chance to be part of a vibrant community that is at the forefront of research in fluid mechanics and its applications in sustainable energy and environmental solutions.

Work duties

The main duties of doctoral students are to devote themselves to their research studies which includes participating in research projects and third cycle courses. The work duties will also/can also include teaching and other departmental duties (no more than 20%).

This doctoral position is centered on the advanced study of Computational Fluid Dynamics (CFD) as applied to Hydrogen Internal Combustion Engines. The primary research focus is on the mathematical and computational modeling of hydrogen fuel dynamics in internal combustion engines, aiming to innovate and optimize engine design for zero carbon emissions. This involves a detailed exploration of the fluid mechanics and thermodynamics specific to hydrogen combustion processes, including turbulence modeling, combustion kinetics, and heat transfer in engine environments. The successful candidate will contribute to a crucial area of research that supports the transition to sustainable, clean energy in heavy-duty transportation, aligning with global environmental goals.

Detailed description of the work duties, such as:

• Conduct CFD simulations to analyze engine performance under different operating conditions,
• Analyze simulation outcomes and compare them with experimental data provided by our industry partners,
• Contribute to developing mathematical models for different processes involved in the high-pressure hydrogen injection, ignition, and combustion,
• Investigate and characterize different technical possibilities for igniting hydrogen under engine conditions,
• Collaborate with interdisciplinary teams and contribute to academic publications and presentations,
• Participate in conferences and workshops to disseminate research findings,

Admission requirements 

A person meets the general admission requirements for third-cycle courses and study programmes if the applicant: 

• has been awarded a second-cycle qualification, or
• has satisfied the requirements for courses comprising at least 240 credits of which at least 60 credits were awarded in the second cycle, or
• has acquired substantially equivalent knowledge in some other way in Sweden or abroad.

A person meets the specific admission requirements for third cycle studies in Energy Sciences if the applicant has:

• at least 90 credits in the subject of the third cycle programme,  of which at least 60 credits are from second-cycle courses of relevance to the subject and 30 credits from a second-cycle degree project of relevance to the subject
• a Master's degree of relevance to the field

Additional requirements:

• Very good oral and written proficiency in English.
• Knowledge of fluid mechanics, turbulent flow 
• Demonstrable experience in computational fluid dynamics (CFD) simulation.
• Strong analytical skills and the ability to conduct independent research.
• A track record of published research in relevant scientific journals is advantageous.
• Ability to collaborate effectively with interdisciplinary research teams.

Assessment criteria

Selection for third-cycle studies is based on the student’s potential to profit from such studies. The assessment of potential is made primarily on the basis of academic results from the first and second cycle. Special attention is paid to the following: 

1. Knowledge and skills relevant to the thesis project and the subject of study.
2. An assessment of ability to work independently and to formulate and tackle research problems.
3. Written and oral communication skills.
4. Other experience relevant to the third-cycle studies, e.g. professional experience. 

Other assessment criteria:

• Knowledge and practical experience in computational fluid dynamics (CFD)
• Knowledge and practical experience in mathematical modeling, such as turbulent-chmistry interactions
• Knowledge of internal combustion engines
• Knowledge in chemistry and reaction kinetics in the gas phase

Consideration will also be given to good collaborative skills, drive and independence, and how the applicant, through experience and skills, is deemed to have the abilities necessary for successfully completing the third cycle programme.
