Gutsul O. Physical principles of devices for measuring electrophysical and rheological parameters of fluids

Thesis is concerned with to research and the theoretical basis of the physical processes in the systems and devices through which define the basic electrophysical and rheological parameters of the fluids and films. In work the advanced new types of electrical methods for the study of liquids and films (electrode and electrodeless) and devices based on them are suitable for the measurement and analysis of biological fluids (blood, plasma). New methods of an automated evaluation of the blood rheological parameters - the viscosity, electric conductivity and the charge of erythrocytes have been theoretically and experimentally substantiated by way of registering the Q-factor of the tuned-circuit, containing a bioinert capillary with the blood flow. Created electrodeless instruments for measuring resistivity and viscosity of small volumes (1 ml) investigated liquids. A design of an electronic measuring complex is based on modeling the physical conditions the movement of the blood in the natural environment. These results have practical significance because they can be used for research and routine control: a) small samples of blood and blood plasma of healthy and sick people for diagnosis in clinical practice, b) electrical and mechanical properties of the metal electrodes aggressive fluids used in technological processes of production of new materials.
