I want to ask how to constructI want to ask how to construct a solver of a radiative heat transfer problem and how to give the boundary condition.
The abstruct of calculation is as follows: The radiation from the sun (or a black body) is heating a pipe. (An intensity and a direction of the radiation are fixed.) Then water flowing in this pipe is cooling the pipe. Under these conditions, I want to calculate a distribution of temperature of water and the pipe. If it is possible, I also want to calculate a distribution of temperature of the air around the pipe. I searched a buoyantSimpleRadiationFoam and a chtMultiRegionFoam. I think I need functions of the both of these two solvers. Have I got to construct new solver? If I do not have to construct new solver, which solver must I choose? |
