A study for multi-layer skin burn injuries based on DPL bioheat model

Abstract

In this paper, multi-layer skin burn injuries are studied using the DPL bioheat model when skin surface is subjected to different non-Fourier boundary conditions. A skin made of three layers known as epidermis, dermis, and subcutaneous layer. These layers assumed to be homogeneous and each layer studied separately. The metabolic heat varies linearly with temperature. The diffusion and evaporation of water in the multi-layer of skin increases heat loss in the skin layer. To solve the BVP of hyperbolic PDE, the FELWG method has been used. The whole analysis presented in a non-dimensional form and the results are shown graphically. In a particular case, the result obtained is compared with the exact solution and is in good agreement. The effects of relaxation time, layer thickness, different temperature, and non-Fourier boundary condition are analyzed at the temperature of the tissue related to the burning of the skin, and the three layers are discussed in detail. © 2020, Akadémiai Kiadó, Budapest, Hungary.
