| Abstract: | Based
on the analysis of biological heat and mass transfer processes, a practical model for
thermal effect on tissue has been developed in this paper. This is a stefan problem with
several interfaces whose thermophysical properties are step-function. One-dimensional
problem has been computed, which can determine the size of vaporized field and the
velocities of moving interfaces and estimate the size of thermal-injury region. Validation
of the model developed here is conducted by comparing the results with experimental data,
and it indicates that the model is in conformity with practical thermal-injury processes. |
