Measurement of the thickness of liquid film by means of capacitance method. Interim report
A technique was developed for measuring water film thickness in a two phase annular flow system by means of the capacitance method. Theoretical considerations are applied to estimate the capacitance value as a function of the film thickness. An experimental model of the flow system with two types of electrodes mounted on the inner wall of a cylindrical tube was constructed and evaluated. The ability of the apparatus to observe fluctuations and wave motions of the water film passing over the electrodes is described.
