摘要

The non-Fourier dual-phase-lag heat model has been solved as a well-known accurate bio-heat model to compute the temperature distribution in a three-dimensional multilayered skin of the human finger including the embedded vessels. A novel conjugate solver over the platform of OpenFOAM codes has been developed. Three types of vessels that are rep-resentor of the capillaries, the small arteries, and the small veins with different diameters, the blood velocity, the blood pressure, and the distance from the skin surface are placed in the epidermis, the dermis, and the hypodermis layers. Numerical simulations were conducted to obtain the temperature distribution and the peak-temperature-rise in the skin layers and the buried vessels by presenting a new three-dimensional multilayered skin heat model. Effect of the buried countercurrent vessels under conjugate heat transfer between the blood vessels and the surrounded layers is included in the model. Influence of these vessels on temperature distribution originated from an external heat source in their surrounding layers, as well as the heat absorption and dissipation have been presented.
