Surface| Summary: | Using the finite integral transformation along the spatial Cartesian coordinates, an analytical expression for calculating the temperature distribution T (x, y, z) due to laser pulses in a solid located in the half-space z<0 is obtained. The numerical calculations show that a uniform warming of the body surface takes place only during a part of the pulse duration. Deep inside the solid, the maximum temperature value compared to the surface takes place with a time delay. This time delay depends on the heat wave propagation velocity. Along with heat penetration into the solid, a maximum temperature zone degradation process takes place. Cooling velocity in the upper layers appears to be higher than that in the deeper layers. However, the cooling period in deeper layers is less than that in upper layers. The results obtained are qualitatively consistent with published experimental data. |
