Abstract

The interconnected processes of transfer of mass, impulse and energy in the electrochemical concentrator of oxygen of the life support systems are considered. It is investigated of electrochemical system at formation no stationary fields of concentration, speeds, deformations, temperatures. The results of computational researches of mathematical model with nonlinear characteristics of a working environment are presented in the form of fields of concentration, speeds, deformations, temperature and normal and tangential components of a pressure. The profiles of tangential component of a pressure, having passed through peak in near-surface area, have character changing a direction. The profiles of concentration of components, speeds, temperature are changed most intensively in frontier area. The results of profiles of concentration and pressure define algorithm of control of operational-technological modes of the electrochemical life support systems.
