Abstract:
The three-dimensional ablation problem for semi-space on the border of which the temperature is set is considered. It is supposed that heat extends with final speed. The decision is represented in the form of a beam number. The arrangement of ablation fronts in the various moments of time are illustratec by schedules.
Keywords:ablation, phase transition, enertia of a thermal stream, a heatstroke, beam number, intensity of rupture, absolute derivative, kinematic and geometrical conditions of compatibility.
