Fractional dual-phase-lag heat conduction model for laser pulse heating

摘要

In the present work, the short-pulse laser heating of a semi-infinite medium is considered. The time fractional dual-phase-lag model is used as the heat conduction model and the corresponding fractional heat conduction equation with a volumetric heat source is established. The semi-analytical solution for the temperature distribution is obtained by using the Laplace transform method. Finally, the influence of pertinent parameters on the temperature distribution is studied graphically.
