Vacant job

Lund University was founded in 1666 and is consistently ranked among the world's leading universities. It has approximately 46,000 students and 8,500 employees in Lund, Helsingborg, and Malmö. We are united in our strive to understand, explain, and improve our world and the conditions of people.

Description of the workplace

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

In the Division of Fluid Mechanics, you will find a diverse team of experts specializing in various aspects of fluid dynamics, heat transfer, and multiphysics problems, all working to develop sustainable solutions for contemporary challenges. Our facilities are equipped with state-of-the-art computational resources, enabling advanced simulations and modeling. Furthermore, we actively engage in collaborations with other leading experts in laser diagnostics, automatic control, heat transfer, and life cycle assessment, both nationally and internationally, fostering a network of expertise and innovation.

This PhD position is part of the interdisciplinary research project OXYFLUID, conducted in collaboration between Lund University, Umeå University, Luleå University of Technology, RISE Research Institutes of Sweden, and several industrial partners. The project combines advanced numerical modeling, laboratory-scale experiments, optical diagnostics, and system analysis to develop and evaluate technologies for oxyfuel combustion in fluidized beds for negative CO₂ emissions and carbon dioxide capture applications.

Job Description

The main task for a PhD student is to pursue their doctoral education, which includes participation in research projects and doctoral courses. The duties may also include teaching and other departmental work, up to a maximum of 20% of working time.

The work involves developing advanced numerical models for reactive gas-particle flows in fluidized bed reactors under oxyfuel conditions. The research will be conducted within an Eulerian–Lagrangian framework and will include the implementation and validation of sub-models for particle transport, fuel conversion, devolatilization, heterogeneous and homogeneous reactions, and the transport of inorganic species such as potassium, chlorine, and sulfur. The project will integrate advanced methods such as Multi-Phase Particle-in-Cell (MP-PIC), coarse-graining methods, distribution-kernel models, and other emerging methods for particle interactions.

The position also involves close collaboration with researchers working on experiments, optical diagnostics, process modeling, and system analysis within the broader OXYFLUID project.

Qualifications

Basic eligibility for doctoral studies is met by those who have:

• completed a degree at advanced level, or
• fulfilled course requirements of at least 240 higher education credits, of which at least 60 credits are at advanced level, or
• acquired substantially equivalent knowledge in some other way, within or outside the country.

The requirements for special eligibility in Energy Sciences are met by those who have:

• At least 30 higher education credits at advanced level relevant to the subject, of which at least 15 credits must consist of an advanced level degree project, or
• A Master of Science in Engineering or a Master's degree in mechanical engineering, technical physics, or a related field.

Other requirements:

• Knowledge in fluid mechanics and reactive flows.
• Documented experience with CFD simulations (Computational Fluid Dynamics) and scientific calculations.
• Programming skills, e.g., in C++, Python, MATLAB, or similar languages.
• Strong analytical ability and capacity for independent research.
• Ability to collaborate effectively in interdisciplinary research environments.
• Very good ability to communicate in spoken and written English.

Merits:

• Documented experience in scientific publication within relevant research areas.
• Knowledge in multiphase flows, combustion, or particle transport.
• Experience with High-Performance Computing (HPC), Eulerian–Lagrangian modeling, or fluidized bed simulations is considered particularly meritorious.

Application Instructions

The application should be written in English. It must include a cover letter explaining why you are interested in the position and how the research project aligns with your interests and educational background. The application should also include a CV, degree certificates or equivalent, and any other supporting documents (copies of grades, contact details for references, recommendation letters, etc.).
