Investigation of the Effect of Low Temperatures on Each Layer of the Skin Using Computer Simulations

In this paper, the question of measuring skin integument under the influence of low temperatures is considered. The effect of low temperatures on each layer of the skin was investigated. A model is simulated that allows one to determine the temperature dependence in each layer of the skin from the time of cryochamber and to monitor the temperature change after seance until the temperature field returns to its original state. The dependence of heat flux loss on the degree of cooling of human skin layers is given. The results were obtained using a mathematical model of heat exchange between the flow of a gaseous medium (a pair of liquid nitrogen) and a biological object in a three-dimensional nonstationary formulation. The study was performed using the finite element method in the Comsol Multiphysics application package. The model includes layers of biological tissue and air. Calculations of heat transfer processes in biological tissue were performed using the Bioheat Transfer module. The dependence of heat flux loss on the degree of cooling of human skin layers is given. The results obtained show the effect of the effect of the duration and extent of the cryotherapy effect effect on its further improvement.
