If an object is heated with a constant power source, the temperature will rise continuously towards a steady state value. In this contribution, the possibility of a temperature rise showing a damped oscillation will be analysed theoretically. It will be shown that such a phenomenon can be observed by a small change of the heat transfer equation describing the convective cooling.
The dual phase model for thermal conduction has been applied to transient measurement of a human tissue. The dual phase thermal conduction is closely related to the non Fourier thermal conduction due to the wave properties of the equation.
In this paper, it is outlined how thermal AC measurements can be carried out on a resistor deposited on an electronic substrate. The AC approach enables us to limit ourselves to phase measurements which can be carried out with a much higher precision than amplitude measurements. It will also be demonstrated how the phase measurements at a well-chosen frequency can be used to measure the heat transfer...
