Mathematical Modeling of the Processes Occurring in Gas Mixtures Used in Hyperbaric Facilities

Diving is one of the domains in which humans are facing a totally different environment from that in which they live normally. Depending on the purpose of the underwater mission and the diving depth to be reached, some special installations and breathable gas mixtures are used to sustain life in such an environment. Diving chambers are hyperbaric facilities used for forming, training, testing and in unfortunate circumstances rescuing divers. The paper deals with the mathematical modeling of the phenomenon taking place in a hyperbaric facility during the compression and decompression phases of a saturation diving. For this purpose the authors of the present paper have conceived a mathematical model with which, the values of the main quantities forming a breathable gas mixtures delivered to the divers are established for each diving depth during the entire mission.
