Optoelectronic measurement of interfacial surface
Czernek K., Witczak S.
pages 177 - 180, full text

The study presents the possible use of optoelectronic system for the measurement of the values which are specific for hydrodynamics of two-phase gas-liquid flow in vertical pipes, where a very-highviscosity liquid forms a falling film in a pipe. The experimental method was provided, and the findings were presented and analyzed for selected values which characterize the two-phase flow. Attempt was also made to evaluate the effects of flow parameters and properties of the liquid on the gas-liquid interface surface value, which is decisive for the conditions of heat exchange and mass transfer in falling film equipment.
