 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 http://civileng.aalto.fi/en/.

 Research

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 to efficiently account for spectral thermal radiation of gases in fires. It will focus on studying the importance of gas, and soot spectral radiative properties in various thermal condition of fires. The need of modifying/correcting the module of radiative properties of RADCAL used in an open source software of fire dynamics simulator (FDS) will be checked and performed.  Accordingly, development and implementation of non-gray global models into open source CFD codes will be done. Studying the hybrid connection of gas radiation solver with flow LES solver, combustion solver and radiation penetration into condensed phase will be done. The computations will be performed using an open-source software Fire Dynamics Simulator (FDS) - the globally most widely used simulation program for fire safety.
