Doctoral Researcher position in Experimental studies on Hydrogen and Methane combustion in Argon
The work will be completed at the Department of Mechanical Engineering in the Energy Conversion and Systems research group. The research work will be completed as part of a multidisciplinary team focusing on internal combustion engine relevant studies, including optical diagnostics in the constant volume chamber, full-metal and optical research engines.
Topic: Optical diagnostics for the hydrogen and methane combustion in argon: This project investigates the combustion characteristics and jet dynamics of ultra-high-pressure (>300 bar) hydrogen and methane injections in argon environments, under engine-relevant conditions. Advanced optical diagnostics, including high-speed Schlieren imaging, Particle Image Velocimetry (PIV), and Planar Laser-Induced Fluorescence (PLIF) will be employed within a custom optical spray and combustion chamber to capture detailed flow and combustion phenomena.
The primary objectives are to visualize and quantify jet dynamics, mixing behavior, ignition delay, flame structure, and overall combustion characteristics in argon environment. The experimental data obtained from Mckenna burner, optical spray and combustion chamber, and optical engine will provide valuable benchmarks for validating Computational Fluid Dynamics (CFD) models of high-pressure, inert-atmosphere combustion. The project is particularly relevant to future low-emission or nitrogen-free power cycles. Prior experience with optical diagnostics or combustion systems is highly desirable.
Requirements
The applicant should have a good experimental track-record with additional background knowledge in some of the following topics:
- Knowledge in internal combustion engine, fluid dynamics, and combustion
- CAD modelling capability to design and modify the facilities, such as nozzles, optical spray and combustion chamber, optical engine, etc.
- Matlab, Python, and other programming languages
- Machine learning or deep learning in image post-processing
- Experience using optical tools, e.g., high-speed cameras, intensifiers, spectrometers, lasers, etc.
The applicant for the position of a doctoral Candidate must have a Master’s degree and must fulfill the requirements for doctoral students at the Aalto University School of Engineering.

Employment
The expected duration of doctoral studies is four years, but a contract is at first made for two years, and the extension depends on candidate’s advancement in her/his studies and research.
The salary for the position is determined according to the salary system for universities used at Aalto University. The starting gross salary for a doctoral candidate is currently €2960 per month, increasing as studies progress and set goals are achieved. (The highest salary level for a doctoral candidate is currently €3662 per month.) The annual workload for research and teaching staff at Aalto University is 1612 hours. The employment relationship at Aalto University is full-time and fixed-term (two years), and it can be extended based on achievements and the availability of funding.
