5 LASER SPOT HEAT TRANSFER ACCOMPANIED BY PARABOLIC TEMPERATURE DISTRIBUTION INSIDE THE ROD
Abstract
The co-authors have solved the problem of an unsteady temperature field inside a structural beam, if one of its ends is exposed to heating. The problem was solved using a traditional Fourier method. The solution derived by the co-authors was verified by the comparison of the final temperature field and the input data. MathCAD-14 software was employed to make calculations and to generate figures. Application of analytical methods, like Fourier series formalism, in combination with computing aids makes it possible to study both qualitative and quantitative constituents of the process of heat redistribution inside structural units in case of exposure to contingency actions. There will be no uniform temperature reduction in the course of intensive cooling of rod ends after the thermal exposure. If the value of the temperature conductivity coefficient is equal to .01, in 12 hours the residual heating may reach 20 % of the initial heating temperature.
