Zusammenfassung: | The invention belongs to the technical field of multiphase flow parameter testing, and provides a gas-liquid two-phase flow parameter measuring method and system based on a conducting probe, the local gas content is calculated according to the ratio of the time occupied by air of the conducting probe to the total measuring time of the conducting probe, the local gas content is accurately measured in a simple mode, and the measuring accuracy of the gas-liquid two-phase flow parameter measuring method and system based on the conducting probe is improved. It is not required to assume that bubbles are spherical or ellipsoidal; meanwhile, when the interface normal vector is determined in the interface concentration calculation process, the interface unit normal vector is expressed through the apparent velocity, and the interface concentration is obtained through calculation according to the reciprocal of the absolute value of the product of the interface unit normal vector and the apparent velocity vector; the pro |
