We are looking for a researcher assistant in the field of computational fluid dynamics (CFD) simulations to join the research group of associate professor Armin Wehrfritz in the Department of Mechanical and Materials Engineering. The task is fixed-term and the starting time of the position is 1.6.2026, or according to mutual agreement. The contract duration will be 6 months from the starting date.

The position is part of a larger consortium research project within the Zero Emission Marine ecosystem funded by Business Finland (https://www.zemecosystem.com). The aim of the overall project is to obtain science-based knowledge on the utilisation of hydrogen as a fuel, enabling the transition to renewable energies. 

The topic of the advertised position is primarily focused on understanding the fluid dynamics and thermochemical processes in heat exchangers and injection system. The candidate will use state-of-the-art simulation techniques, namely 3d Reynolds-averaged Navier—Stokes (RANS) and large-eddy simulation (LES), to study fluid dynamics, heat transfer and phase change in practically relevant configurations. 

Requirements  

Successful candidates should have a B.Sc. degree in mechanical/aerospace engineering, physics, mathematics, or a closely related field. Courses on computational simulation or computational fluid dynamics are considered highly beneficial.

The task is aimed at Master’s degree students of mechanical engineering (or a suitable field). It is noted that applicants must be registered as a present student. In the selection process, we prioritize our own MSc students at the university of Turku.

The following skills are essential for a successful completion of the project:    

• Knowledge of numerical methods in engineering, physics and mathematics
• Python, Matlab, C++, Fortran or other relevant programming languages
• Solid understanding of fluid mechanics and basic knowledge in CFD
• Ability to work with complex numerical simulation software packages
• Excellent academic track record
• Excellent presentation skills 

Additional skills considered beneficial for the work are:

• Experience with OpenFOAM and mesh generation tools

Salary details

The salaries are determined in accordance with the University salary system for teaching and research personnel, which consists of a requirement level and a personal performance percentage. For a Research Assistant, the requirement level is at level 1. The personal performance component, added on top of the task-specific base salary is also paid. The salary will be commensurate with qualifications and experience and will be approximately 2400 €/month.

The position is subject to a trial period of three (3) months.
