Abstract

See full text

A temperature sensing device comprising a plurality of thermocouples in a hollow tube, where the thermocouples sensing tips contact the outer wall of the tube, and a heat flux source that heats the hollow tube. The hollow tube is inserted through a cross section of a pipe perpendicular to the longitudinal axis of the pipe. The apparatus measures a void fraction in a two-phase flow of a liquid-gas mixture flowing through the pipe. A process of measuring void fraction whereby the hollow tube is heated to an initial temperature, and in the presence of a liquid-gas mixture flow through the pipe the difference is calculated between the initial temperature of the tube and the temperature during liquid-gas mixture flow, to determine the void fraction in the two-phase flow of liquid-gas mixture through the pipe.
