High temperature turbulence: Coupling of radiative and convective heat transfer in turbulent flows

Radiative heat transfer has a large influence in engineering systems, especially when the temperature involved is elevated. For this reason a correct assessment of heat transfer in presence of radiation is of great importance in high temperature and pressure equipment such as combustion chambers, heat exchangers as well as reentry vehicles and rockets. This thesis presents the results of innovative coupled radiative heat transfer and turbulence simulations, which aim at investigating turbulence-radiation interactions and the effect of radiation in the turbulent heat transfer process. The simulations are performed employing heterogeneous high performance computing systems in which the radiative heat transfer is solved on graphical processing units while the fluid flow is solved on CPUs.
