Abstract

The paper presents the results of computer simulation of the working tool of thermoelectric device for cryodestruction without taking into account phase transition, as well as cyclic temperature effect on the human skin in dynamic mode. A physical model of the working tool, a three-dimensional computer model of biological tissue taking into account thermophysical processes, blood circulation, heat exchange, metabolic processes and phase transitions, is constructed. As an example, a case is considered when the working tool is on the skin surface, the temperature of which changes cyclically according to a given law in the temperature range [– 50 ÷ + 50] °C. Temperature distributions in different layers of the human skin in cooling and heating modes were determined. The obtained results make it possible to predict the depth of freezing and warming of biological tissue at a given temperature effect.
