Abstract
Drilling speed and drilling efficiency is studied by using the unsteady model of dynamic 1-D. The damage in the vapor and liquid leaving time is studied due to the material interaction of laser. The Interface places of liquid – solid and vapour are obtained by solving the formulas and energy conservation equations in the relations. The dependence of saturation temperature to the mutual pressure for the use of the Clausius–Clapeyron equation is considered. Transitive heat loss of solid is in this model and is solved by using an approximate total method. The results indicate that the fraction of heat which from the transfer through the solid is very small and its impact on evaporation is not important. In other words, the transitive heat loss greatly reduces the thickness of the liquid layer, which after drilling, a new layer is recast.
