Abstract :
We have been developing two computer codes in order to evaluate non-equilibrium thermophysical characteristics of the vapor from the plasma-facing materials (PFMs). One of these codes is a finite difference code for solving the three-dimensional Boltzmann-Krook-Welander [3D-BKW] equations that assume the material vapor phase as a fluid, and the other is a three-dimensional direct simulation Monte Carlo [3D-DSMC] code. Some numerical results by using the 3D-BKW code for the vapor temperature and density distributions of the PFMs at high temperature are compared with the results by using the 3D-DSMC code
