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.

在本文中，当皮肤表面经受不同的非傅立叶边界条件时，使用DPL生物热模型研究多层皮肤烧伤。由三层组成的皮肤，称为表皮，真皮和皮下层。假设这些层是同质的，每个层分别进行研究。代谢热随温度线性变化。水在皮肤多层中的扩散和蒸发增加了皮肤层中的热损失。为了解决双曲型PDE的BVP，已使用FELWG方法。整个分析以无量纲形式显示，结果以图形方式显示。在特定情况下，将获得的结果与确切的解决方案进行比较，并且吻合良好。弛豫时间，层厚，不同温度，
