Bioheat transfer problems with spatial or transient heating on skin surface or inside biological bodies

A bioheat transfer model with quadratic temperature-dependent thermal conductivity is considered in this work. Applying the Taylor expansion method, we have investigated the bioheat transfer problems with generalized spatial or transient heating both on skin surface and inside the biological bodies. The effect of the temperature-dependent thermal conductivity on the nonlinear temperature distribution is studied. The method used in this paper can be useful to investigate several typical bioheat transfer processes, which are often encountered in cancer hyperthermia, laser surgery, thermal comfort analysis, and tissue thermal parameter estimation.
