Doctoral Candidate in Numerical Modelling of Thermal Radiation in Fires

The Department of Civil Engineering is seeking an outstanding Doctoral Candidate for research on advanced modelling of thermal radiation in fires. The doctoral candidate position is available in the Fire Safety Engineering group. For more information of the research and teaching at the department, go to More information on the Fire Safety Engineering group activities at


Thermal radiation is the dominating mode of heat transfer in large fires. Numerical models for the radiation emission, transport and attenuation in absorbing and scattering media are key elements in the state-of-the-art, CFD-based fire simulation software. These computer programs are used for the research and engineering applications of the fire safety design and risk analyses.

The research will focus on developing the numerical methods for transfer of spectrally resolved thermal radiation. In the first stage, an existing computing method (Full-Spectrum Correlated-K), developed originally for the efficient computation of gas phase radiation, will be extended for liquid layers, targeting at improved accuracy of liquid pool heat transfer and burning rate predictions. Small-scale laboratory experiments are performed for material characterization and model validation. In the second stage, an optimized gas-phase version of the same method will be developed for the fire simulation purposes. The computations will be performed using an open-source software Fire Dynamics Simulator (FDS) – the globally most widely used simulation program for fire safety.


Required background: The candidate should have an MSc degree in physics or mechanical engineering (heat transfer and combustion), with excellent or very good grades.

Expected skills and knowledge: Programming skills and the knowledge of computational techniques and numerical method in general are essential requirements. Capability to collaborate in an international research community with English language is also needed.

Contract and salary

The doctoral candidate position is contract-based; one year contract is granted first, followed by a possible extension of a three-year period depending on the achievements during the first contractual period and on an admission to do postgraduate studies in the School of Engineering.

In a maximum of four years, the doctoral candidate is required to 1) complete the doctoral dissertation, 2) finish relevant courses for 40 ECTS credits and 3) participate in teaching. The applicant must fulfill the requirements for entitlement to do postgraduate studies at Aalto University:
