چکیده:

Temperature prediction in biological tissues irradiated by an optical source is frequently required in some medical applications, like Thermotherapy, Hyperthermia and tissue ablation. One of the most difficult problems of heat transfer estimation in living system is the assessment of the effect of blood circulation. In order to evaluate transient convective heat transfer between the tissue and blood vessels, temperature distributions in three-dimensional space are obtained by solving continuity, momentum and energy equations numerically. In this paper, ANSYS-CFX is used for numerical solution. In addition, we consider the skin as a three-dimensional structure including three layers embedded with multi-level blood vessels, i.e. artery and vein. The countercurrent vessels, with circular cross section area, are considered to beoptimally branched.
