This study investigated the wall radiative heat flux (WRHF) of air- and oxy-coal combustion in a simple hexahedral furnace and in a 100 MWe single-wall-fired boiler using computational modeling. The hexahedral furnace had similar operation conditions with the boiler, but the coal combustion was...
Dear Foamers, I would like to know how can I do to make wallHeatFlux utility takes into account the radiative heat flux, since I found out it doesn't
Radiative Heat Deposition Analysis of Fusion Reactor First Wall by Monte Carlo Transport Codedoi:10.1080/18811248.1981.9733257Heat flux distribution on the first wall of a fusion reactor due to the thermal radiation from high temperature protection wall placed in front of the first wall was analyzed....
I am currently approaching multiphase flow modelling in FOAM, and for heat transfer I intend to introduce a mixed convective and radiative boundary condition for phases' temperature. It looked to me that the BC externalWallHeatFluxTemperature could properly represent the physics, but...

The significance of this length scale has been verified by the experimental results for flame heights and heat fluxes and by observations. A similarity correlation for flame heights between the two parallel walls were developed in this research. Similarity correlations for radiative heat fluxes on ...

Furthermore, MILD combustion has a larger total heat flux comparing to the conventional mode, mainly from the higher radiative heat transfer. 展开 关键词: MILD combustion Non-preheated air Combustion stability CO emission Chemical reaction rate Heat transfer ...
If, for a start, I want an adiabatic wall, the zeroGradient boundary condition as in the hotRadiationRoom tutorial does give zero convective heat flux at the wall, but it does not touch the radiative heat flux. Can this be implemented in some other way, if externalWallHeatF...
