title: [Simulation models of thermal-humidity parameters of the space suit].
abstract: The paper describes a mathematical model of and methods of calculating thermal-humidity fields in a spacewalking suit. The authors made an integral calculation of thermal and mass transfer in the spacesuit. A system of equations is solved analytically and numerically with the use of a combined method. As a result of model calculations, determined were integral spacesuit characteristics including total amount of rejected heat, heat rejected by the WC suit, humidity rejected by ventilation, and humidity accumulated in different spacesuit layers. Comparison of calculation and experimental data for spacesuit Orlan showed that maximal differences in temperature, humidity, thermal and humidity flows, and other system parameters did not exceed 13%.
