On non-fourier temperature wave and thermal relaxation time

In this paper, the non-Fourier effects in a material under heating flux with an actual pulse and periodic temporal profile are investigated after introducing the physical mechanism of the thermal relaxation model. By using the analytical solution of the non-Fourier hyperbolic conduction equation, a discussion about the wave characteristics of non-Fourier conduction is given, and the manner in which relaxation time affects the temperature behavior is discussed. Then a measuring method for the relaxation time is suggested for these two kinds of heating flux.
