Web17 mrt. 2009 · In this paper, we present a one-dimensional (1D) melting, evaporating, and resolidifying model describing the interaction of a scanning laser beam with a metal surface wherein the continuous and stepwise heat flux is applied. One set of 1D conduction equations, which is valid in all phases including solid, liquid, and vapor, has been … WebOn the USMP-2 and -3 missions in March 1994 and February 1996, IDGE used succinonitrile (SCN), an organic fluid that is clear both as a crystal and a liquid, and is a good model for iron-based metals. On the USMP-3 mission in late 1997, it used pivalic acid (PVA), another clear organic, that is a good model for non-iron metals.
