About this position

Chalmers University of Technology invites applications for a doctoral project in multiphase flow within the Multiphase Group at the Division of Fluid Dynamics, Department of Mechanical Engineering, in Gothenburg, Sweden.

The research investigates whether the random motion of tiny particles can reveal information about their surrounding environment. The project will examine how Brownian motion is shaped by fluid flow, heat and mass transfer, and chemical reactions in confined environments. By combining fundamental fluid dynamics with nanoscale diagnostics, the work will develop new ways to infer chemical reactivity from observable particle motion.

The doctoral researcher will use particle-resolved direct numerical simulations (PR-DNS) to uncover the physical mechanisms linking particle dynamics to local fluid and chemical conditions. The position offers an opportunity to develop scientific concepts, communicate research findings, and work with experienced researchers in a division conducting numerical and experimental research on turbulent, incompressible and compressible, single-phase and multiphase flows.

The student will join the Graduate School of Thermo- and Fluid Dynamics and contribute to a research environment connected to both fundamental science and industrial collaboration. The role may also include undergraduate teaching or related departmental duties.

Funding details

The doctoral position is fully funded from the start. It is a fixed-term four-year appointment, extendable to five years when teaching or other duties comprise up to 20% of working hours. The starting salary is 35,725 SEK per month, valid from 1 May 2026. The doctoral student is employed by Chalmers and receives employee benefits.

What's required

Applicants must have a Master's degree of 120 credits or a 60-credit magisterexamen in Mechanical Engineering, Engineering Physics, Chemical Engineering, Applied Mathematics, or a related field; for education earned outside Sweden, a four-year Bachelor's degree is accepted. Strong written and verbal English communication skills, scientific programming proficiency, curiosity about physical-world phenomena, and motivation to investigate unanswered questions collaboratively are required. Experience with computational fluid dynamics or numerical simulation, numerical model development, particle dynamics, stochastic processes, heat and mass transfer, high-performance computing, or parallel computing is advantageous.

How to apply

Apply through the online application form linked on the vacancy page by 13 December 2026. Submit English-language PDF files containing a CV, personal letter, bachelor's and available master's thesis, and transcripts; each file must be no larger than 40 MB, and applications by email or incomplete applications will not be considered.
