Abstract :
In this study, we presented an experiment to obtain the thermal relaxation time which is necessary to model heat conduction by the hyperbolic heat equation. This experiment was evaluated by finite element simulation to acquire reliably this parameter for biological tissue. Besides that, we measured the thermal relaxation time of agar-gelled water with 2% of concentration at 25°C. The average value of thermal relaxation time for the gel was 7.9630s with standard deviation of 1.4562.
