Burylova N. Mathematical simulation of hydrodynamics, heat-mass exchangeprocesses in electrochemical systems.

The objectis the motion of chemically reacting fluid that conducts current.The aim is the development of mathematical models, techniques, algorithms and programs for mathematical simulation of fluid dynamics and heat-mass exchange in the electrochemical systems.Investigation methods are mathematical simulation and numerical techniques. For the first time on the base of equations of hydrodynamics, electrodynamics, chemical kinetics and convective heat exchange mathematical model for the basic hydrodynamicall and heat- mass exchange processes in the electrochemical systems is constructed. Techniques, algorithms and programs for calculation of the nonstationary mass exchange in the electrolitical fluids are developed , realized, verified and tested. A system of simplifying assumptions for a general mathematical model is formed. Exact solution for the problems approximating the comprising physical processes in the electrochemical fluids are found. Practical importance of the investigation lies in the fact that techniques for simulating the basic physical and chemical processes in the electrochemical cells are developed and realized. The results received have been put to use under developing the design of the new types of batteries at ZAO * VESTA- DNEPR* . The technique proposed can be used in computational hydrodynamics, in a practice of electrochemists under designing the lead- acid batteries and under the high-school studies.
