A unique program for modeling the thermoregulation of the human body has been created at Novosibirsk State Technical University (NSTU). It takes into account the thermal resistance of protective clothing in low-temperature conditions. The development is important for the recovery of athletes, pilots, and cosmonauts after prolonged exertion.
In the program, the body is represented as a system of cylindrical elements, including arms, legs, chest, and abdomen. Each element consists of three layers: muscle tissue, adipose tissue, and subcutaneous capillaries, and also includes a fourth layer — the thermal resistance of protective clothing.
For calculations, a set of equations is used that takes into account thermal balance, heat transfer, and thermal conductivity. The program is capable of estimating the temperatures of various layers and heat loss during cooling, taking into account gender, age, physical activity, and environmental characteristics.
The technology allows modeling cooling in air at temperatures from -50 to 0 degrees, in water from 0 to +20 degrees, and also in a cryosauna with nitrogen at -150 degrees. The multilayered and multi-element approach to research has received positive feedback from specialists at the Moscow Aviation Institute.
