Postdoctoral position in COMPEL-Energy Sciences with a focus on thermal runaway modeling

Lund University was founded in 1666 and is repeatedly ranked among the worlds top universities. The University has around 46 000 students and 8 500 staff based in Lund Helsingborg and Malmö. We are united in our efforts to understand explain and improve our world and the human condition.

The position is located at the Division of Heat Transfer at the Department of Energy Sciences. At the division we conduct research and education on the energy generation conversion and utilization in different electro- and thermo-mechanical systems where the study of heat transfer fluid mechanics reactive flows as well as solid mechanics plays a central particular improved understanding of turbulent reactive and multiphase flows together with material sciences and novel manufacturing techniques is the key to improved heat transfer mechanisms and more efficient use of energy. Approximately 25 colleagues work at the division including 15 PhD students. On the international level we collaborate with universities and institutes in Europe Asia and North America. More information about the Division of Heat Transfer can be found here: COMPetence for the ELectrification of the transport system is a strategic initiative by the Swedish government aimed at strengthening research and educational environments within battery technology and electrification. Within COMPEL the three institutions - Chalmers University of Technology Lund University and Uppsala University in consultation with Swedish industry deepen their collaboration with the aim of strengthening Swedens position in battery technology contributing to the electrification of the transport sector and related areas. The three institutions aim to enhance research and education in the battery sector to ensure strong research in battery technology supporting that electrification of the transport sector is maintained and further developed in Sweden. Research within COMPEL spans the entire battery value chain: materials research research on new cell concepts and cell manufacturing battery systems and system integration recycling and safety.

At Lund University with the Faculty of Engineering (LTH) COMPEL is a strategic initiative aimed at enhancing research environments in battery technology and electrification in a manner that complements relevant research at other institutions and builds on our strengths. COMPEL at Lund University initially includes researchers from ten departments and three areas of research have been identified for strategic development: materials research integration of batteries with power electronics and safe energy storage. On the educational side the number of students in several of the Master programs is being increased and the course offerings related to battery technology and electrification are being strengthened.

This environment is a smorgasbord of resources and opportunities for those who wants to develop their careers and make a difference in the transition towards a sustainable future.

This project focuses on the development of GPU-accelerated high-fidelity thermal runaway simulation models for lithium-ion battery cells modules packs and complete battery systems. Thermal runaway is a chain reaction that leads to the uncontrolled release of energy stored within a battery cell potentially resulting in fires and other hazardous events that are difficult to mitigate. As battery systems grow in size and complexity there is an increasing need for computationally efficient predictive tools capable of resolving the underlying physical and chemical processes across multiple scales.

The project will be undertaken in collaboration with Scania Industrial Battery Systems and the partners of the COMPEL initiative. The primary goal of the postdoctoral project is to develop next-generation GPU-based simulation methodologies in OpenFOAM for predicting thermal runaway initiation and propagation at the cell- and module level. Particular emphasis will be placed on leveraging modern heterogeneous computing architectures to enable large-scale high-fidelity reacting-flow simulations. The models developed at the cell level will subsequently be coupled to module- pack- and system-level simulations to improve the prediction of thermal runaway propagation in practical battery systems.

The main duties involved in a post-doctoral position is to conduct research. Teaching may also be included but up to no more than 20% of working hours. The position includes the opportunity for three weeks of training in higher education teaching and learning.
