摘要

Although very important, the freezing burns caused by extremely low temperature have received few attentions up to now. In this study, a three-dimensional multi-layer bioheat transfer model is developed to predict the tissue damage following a freezing burn. This mathematical model is numerically solved using finite-difference method. The results indicate that the production of freezing burns is dependent on both the surface area exposed to cold medium and the duration of exposure to freezing. Further, a preliminary experiment is also conducted to validate the theoretical results. The experimental results qualitatively agree with the theoretical ones.
