Abstract:

In the simulation of line-heating process, the convection boundary condition, especially the subcooled water forced convection, has great influence on the result. The calculation of the convection coefficient is a difficult problem in the simulation. This paper uses the theory of forced convection boiling to study subcooled water forced convection during the line-heating process. By solving the wall temperatures of originating nucleate boiling and critical heat flux for subcooled water and comparing the plate temperature with these two wall temperatures, the status of water can be determined, and then the corresponding convection coefficient is calculated. The simulation results show that the precision of the forced convection boiling boundary condition presented in this paper is much better than that of a boundary condition based on the pool boiling curve.
