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
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.
