Curious about how the world works? So are we. Join the Multiphase Group at Chalmers and help us push the boundaries of fluid dynamics through curiosity-driven, cutting-edge research!
About us
This position is placed at the Division of Fluid Dynamics, which belongs to the Department of Mechanical Engineering.
At the Department of Mechanical Engineering, we unite the power of technology, people, and society to drive the transition toward a sustainable future. Through research, education, and collaboration, we create solutions that connect materials to mobility, ideas to impact – shaping a resilient and sustainable world.
At the Division of Fluid Dynamics, our mission is to gain fundamental knowledge about turbulent incompressible and compressible, single and multiphase flows through numerical and experimental research. We develop new and improved computational and experimental techniques for the study of such flows in both fundamental and real-world environments. Our applied research is carried out in close cooperation with industry, both in national and in international projects.
About the research project
Can the random motion of a tiny particle reveal what is happening in its surroundings? This project explores how Brownian motion is shaped by fluid flow, heat and mass transfer, and chemical reactions in confined environments. Using particle-resolved Direct Numerical Simulations (PR-DNS), we will uncover the physical mechanisms linking particle dynamics to their local environment and develop new ways to extract information about chemical reactivity from observable particle motion. The work combines fundamental fluid dynamics with new opportunities for nanoscale diagnostics.
Who we are looking for
The following requirements are mandatory:
- To qualify as a Doctoral student, you must have a Master's degree (masterexamen) of 120 credits or a Master’s degree (magisterexamen) of 60 credits* in Mechanical Engineering, Engineering Physics, Chemical Engineering, Applied Mathematics, or a related field.
- Strong written and verbal communication skills in English.
- Proficiency in scientific programming.
- A genuine curiosity about how the physical world works, combined with the motivation to explore unanswered questions together with others.
*for students with an education earned outside of Sweden, a 4-year Bachelor’s degree is accepted.
The following experience will strengthen your application:
- Experience with computational fluid dynamics (CFD) or other numerical simulation methods.
- Experience in developing, implementing, or extending numerical simulation models.
- Knowledge of particle dynamics, stochastic processes, or heat and mass transfer.
- Experience with high-performance computing or parallel computing.
What you will do
- Take courses at an advanced level within the Graduate school of Thermo- and Fluid Dynamics.
- Develop your own scientific concepts and communicate the results of your research verbally and in writing.
- The position generally also includes teaching on Chalmers' undergraduate level or performing other duties corresponding to 20 percent of working hours.
- Work closely with experienced researchers who will support and guide your scientific development.
Contract terms
- The Doctoral student positions are fully funded from start.
- The position is a fixed-term appointment of four years, with the possibility to teach up to 20%, which extends the position up to five years.
- A starting salary of 35,725 SEK per month (valid from May 1, 2026).
- Doctoral studies require physical presence throughout the entire study period. A valid residence permit must be presented by the study start date; otherwise the admission may be withdrawn.
What we offer
- As a Doctoral student at Chalmers, you are an employee and enjoy all employee benefits. Read more about working at Chalmers and our benefits for employees.
- A dynamic and inspiring working environment in the coastal city of Gothenburg.
- Read more about Sweden’s generous parental leave, subsidized day care, free schools, healthcare etc at Move To Gothenburg.
Chalmers is dedicated to improving gender balance and actively works with equality projects, such as the GENIE Initiative for gender equality and excellence. We celebrate diversity and consider equality and inclusion as fundamental aspects of all our activities.
