A bio-heat transfer equation was developed based on the dual-phase-lag model for considering the effect of micro-structural interaction. This work employs the corresponding equation to analyze the bio-heat transfer problem in skin, which was regarded as a tri-layer composite. Comparison of the present results with the results from the Pennes model and thermal wave model of bio-heat transfer is made. As stated in the literature, the DPL model would reduce to Fourier's law as τq = τT. However, another literature does not completely agree with it. This controversy would be reviewed in the present work. Also, the conclusion that the DPL bio-heat conduction equation with the effect of blood perfusion can be reduced to the Fourier bio-heat conduction equation only if both τq and τT are zero was made in the literature. The authors are very interested in such a conclusion, and it becomes one of studying points of the present work.
► The dual-phase-lag bio-heat transfer in multi-layer living tissues is explored.
► The controversy on the dual-phase-lag behavior between the literature is reviewed.
► The DPL model of bio-heat transfer can be reduced to the Pennes model for τq = τT.
