Radial Heat Conduction in Laser Heating of Material Slabs.
Abstract
To quantify the cases in which radial heat conduction is important, this report investigates the heating of metal slabs by laser beams with beams with finite diameters. A two-dimensional approach is taken which assumes cylindrical symmetry, and the method of finite differences is used to determine temperature profiles in the slabs as a function of time and incident flux intensity. The times necessary to induce melting at the front surface of the slabs are obtained in the two-dimensional approach and compared with the times obtained in the one-dimensional approach. This gives a direct indication of the importance of radial heat conduction. (Author)
