Synergetic Analysis of the Mass and Electric Transfer Processes in the Electrochemical Systems of the Life Support of Cosmonauts (Miners, Submarines, Rescuers) 961412

In addition to the purely design aspect of utilization of new principles of functioning the searching of ways for process intensification in the life support electrochemical systems is linked to the study of self-organization and stability of the existing working processes in the modes of fluctuations or transients.
Stability analysis of the electrochemical systems (EChS) and establishment of causes of instability outsetting are usually based on the small parameter method or on investigation of eigenvalues of the characteristic equation of mass transfer assuming immobility of the diffusion layer.
The system of water purification from the atmospheric moisture condensate of the long-life orbital stations was chosen as a typical object of study.
The broad spectrum of admixtures (up to 400 names) and duration of the autonomous existence put forward a problem of the complex evaluation of the operational mode stability as well as assessment of the EChS self-organization for the known energy constraints.
The proposed approach uncovers the instability mechanisms and exposes the ways of their elimination when studying the interaction mechanism of transfer processes.
In the case of boundary perturbations the energy estimation defines their suppression by the self-regulating processes.
The integral dissipation function method allows to estimate energy expenses on bringing system back to the original state and define acceptability of the proposed operational mode.
