This first book comprises three parts. Part A covers transport phenomena in electrolytes whereby special attention is given to the more concentrated solutions met with in practice. Examples are given for the calculation of transport parameters in binary and ternary systems. Problems of current density distribution in electrolysers used for electrode processes controlled by charge transfer are solved in Part B by various calculation methods. Special attention is paid to the problems of electrochemical machining and of the current distribution in the Hull cell. Part C is devoted to transport phenomena at plate electrodes and diaphragms with special regard to hydrodynamics, and hence to electrode processes controlled by mass transfer. Equations for the calculation of fluxes of ions and heat to a plate electrode are solved under various conditions, and equations for the transport of ions through diaphragms and ion-exchange membranes are analysed. Much information is presented in the form of figures, diagrams, tables and references.
