Summary
The problem of the phase change produced in semi-infinite media by volume heat sources is considered for quasi steady state conditions and where the molten or sublimated material is removed as soon as it is formed. A general formal solution for the temperature distribution and the velocity of the phase change surface is presented, and it is shown that for source functions of physical interest the velocity of the surface is the ratio of the total heat flux to the energy required to produce the phase change of a unit volume of material. Several examples are considered.
