Abstract

An axisymmetric micro-domain subjected to the ultrashort laser pulse is considered. To describe the process of heat conduction occurring in the analyzed domain, the two-temperature hyperbolic model together with the isothermal solid-liquid and liquid-vapor phase changes is applied. This model, consisting of four equations describing the electrons and lattice temperatures and also the electrons and lattice heat fluxes, is transformed to the model consisting of only two equations describing the electrons and lattice temperatures. Derived equations together with the appropriate boundary and initial conditions, are solved using the finite difference method supplemented by additional numerical procedures which allow to take into account the phase changes. In the final part of the paper the results of computations are shown and the conclusions are formulated.
