2-DIMENSIONAL HYPERBOLIC HEAT-CONDUCTION IN AN ORTHOTROPIC MEDIUM

Many natural and man-made materials have the properties of varying the rmal conductivity with directions. In the present work, the very short -time temperature response characteristics are examined by using a hyp erbolic heat conduction model in an orthotropic medium when an axially symmetric heat flux with a temporal profile, which is either continuo us or activated for period Delta t, is applied. The ratio of the therm al conductivities is one of the important parameters to be considered. The non-Fourier temperature responses in the orthotropic medium are c ompared with those in the isotropic case. The Fourier's results are al so included and compared with the non-Fowrier's results.
