У роботі наведено результати комп’ютерного моделювання процесу кріодеструкції шкіри людини з врахуванням теплофізичних процесів, кровообігу, теплообміну, процесів метаболізму та фазового переходу. Побудовано фізичну, математичну та комп’ютерну моделі шкіри людини, на поверхні якої знаходиться охолоджуючий елемент при температурі -50°C. Визначено розподіли температури і теплових потоків у шкірі людини в режимі охолодження. Отримані результати дають можливість прогнозувати глибину промерзання шкіри і, відповідно, біологічної тканини при заданому температурному впливі. Бібл. 29, рис. 7.
The paper presents the results of computer simulation of human skin cryodestruction process with regard to thermophysical processes, blood circulation, heat transfer, metabolic processes and phase transition. The physical, mathematical and computer models were built for human skin, on the surface of which there is a cooling element at a temperature of -50 ° C. The distribution of temperature and heat fluxes in human skin was determined in cooling mode. The obtained results make it possible to predict the depth of freezing of the skin and, accordingly, biological tissue at a given temperature effect.
