Transient State Finite Element Model to Analyse Thermal Variations in Peripheral Region of Human Limb undergoing Healing after Surgery

The temperature distribution in human tissues is significantly affected by the introduction of an abnormality. The study of temperature distribution in different layers of peripheral tissue is intended to contribute in the diagnosis of many disorders in various organs. In this paper, an axisymmetric one dimensional model has been developed to study transient state temperature distribution in different layers of normal and post surgery peripheral (abnormal) tissues of human limb. Taking into account the variable physiological parameters in dermal layer of peripheral region, the well known Pennes’ bio heat equation is used to analyse and compare the time-dependent temperature distribution of normal and abnormal tissues using finite element technique. A computer program in MATLAB has been developed to simulate the results.
