Job Description

Are you intrigued by the prospect of applying your expertise in computational fluid dynamics (CFD) to model gas flows and temperature distributions? If so, we have an exciting opportunity for you.

Within our European Research Council project, we're delving into electrochemical measurements within a transmission electron microscope (TEM) to explore the structure and composition of operating solid oxide fuel and electrolysis cells (SOEC/SOFC). In these intricate experiments, precise temperature control is paramount.

The temperature regulation of the TEM sample relies on a heater element embedded in a small micro-electromechanical system (MEMS) chip, which also serves as the support for the sample. While past projects have examined temperature distributions over MEMS chips in vacuum conditions, our focus is on understanding the potential impact of flowing gases within the microscope chamber on temperature, especially at a local level directly over the TEM sample.

To tackle this challenge, we're seeking a candidate with strong expertise in CFD modelling, preferably with experience in simulating low gas pressure conditions (the total gas pressure in the microscope chamber being a few mbar). Your role will involve collaborating closely with another team member who will conduct temperature measurements in the Environmental Transmission Electron Microscope (ETEM) for comparison with your modelling results.

This project is part of the ERC project HEIST, where we've pioneered a unique operando TEM method enabling the analysis of material degradation in SOEC/SOFC. Our findings suggest the presence of localized temperature variations within our miniature cells, emphasizing the critical need to quantify and manage these variations effectively.

Responsibilities and qualifications
As a key member of our team, you'll spearhead CFD modelling efforts, drawing on your solid experience in modelling gas flows and temperatures. Ideal candidates should possess:

• Strong competences in CFD modelling
• Experience with simulations of gas flows
• Proficient communication skills in English, both written and verbal
• Demonstrated ability to work independently
• A proactive approach to problem-solving, capable of identifying new directions and opportunities within the project

As a formal requirement, candidates must hold a PhD degree (or equivalent). 

Join us in unravelling the complexities of electrochemical processes within the TEM environment and shaping the future of SOEC/SOFC research.

DTU Energy is focused on education, research, and development within functional materials and their application in sustainable energy technologies. In a sustainable energy system, a large part of the energy will be supplied by fluctuating sources such as solar and wind power. This makes it critically important to be able to convert and store the energy as needed. Our research areas include fuel and electrolysis cells, solar cells, and batteries as well as advanced filtration devices. We are ca. 250 employees. Additional information about the department can be found on  http://www.energy.dtu.dk .

Technology for people
DTU develops technology for people. With our international elite research and study programmes, we are helping to create a better world and to solve the global challenges formulated in the UN’s 17 Sustainable Development Goals. Hans Christian Ørsted founded DTU in 1829 with a clear mission to develop and create value using science and engineering to benefit society. That mission lives on today. DTU has 13,500 students and 6,000 employees. We work in an international atmosphere and have an inclusive, evolving, and informal working environment. DTU has campuses in all parts of Denmark and in Greenland, and we collaborate with the best universities around the world.
