AC electric sensing of slug-flow properties with exposed gold microelectrodes

Popis výsledku v původním jazyce

A new method for slug-flow (segmented flow) characterization by means of ac electric sensing is proposed. Water segments regularly dispersed in kerosene are used as an experimental system. The sensing procedure is carried out in a plexiglass microchip with embedded gold microelectrodes. The presence of passing slugs over a measurement spot is determined from impedance variations. A square-shaped signal resulting from the slug flow is acquired and flow properties such as the mean velocity and length of the slugs are calculated. Complex behaviour of the corresponding electrochemical system is studied. Dependence of the impedance signal on the flow rate, ion concentration in the dispersed water slug and electric field strength are discussed and explainedin detail. Advantages and disadvantages of the suggested method, in comparison with existing capacitive noncontact methods, are also clarified. Unlike the noncontact methods of electric sensing, with the insulation dielectric layer over t
