pages 290 - 293, full text

In the paper a description of heat transfer in a one-dimensional metal films is considered. The Boltzmann transport equation and a two-temperature model supplemented by appropriate boundary and initial conditions are applied to analyze the thermal process in a heated thin metal film. The problem considered is solved by the lattice Boltzmann method and the finite difference method respectively. The internal heat source is given in two different ways. In the first way, the internal heat source is considered a constant value, while in the second way an exponential function which simulates irradiation using a laser pulse is used. In the final part of the paper numerical examples of comparison of two methods and conclusions are presented.
