To analyze heat transfer process in skin tissues subjected to hot water and thus to predict the extent of scald.
Basing on Pennes' Bio-heat Equation, a model for characterizing the damage process in tissues was presented and used for its analysis.
Temperature distribution in the tissues during the process and the time of beginning of scald were numerically obtained. It was found that the effects of different initial temperature distribution, convection coefficients between the hot water and the tissue surfaces, and the temperature of the hot water are significant.
The transient heat transfer behavior in multi-layer tissues subjected to hot water can be predicted by the present model. It is useful in the clinical diagnosis and therapy for the scald caused by hot water.
分析皮肤组织在热水作用下的热传递过程，从而预测烫伤程度。
基于佩恩斯生物热方程，提出并使用了一个表征组织损伤过程的模型进行分析。
通过数值计算得到了该过程中组织内的温度分布以及烫伤开始的时间。发现不同的初始温度分布、热水与组织表面之间的对流系数以及热水温度的影响显著。
该模型可预测多层组织在热水作用下的瞬态热传递行为。它对热水烫伤的临床诊断和治疗具有重要意义。
