The invention provides a method for measuring gas-liquid-solid three-phase separation holdup based on ultrasonic tomography, and relates to the field of fluid detection. The method includes collecting the distance between the gas phase and the liquid phase in the pipeline to obtain the gas phase holdup; performing ultrasonic tomography imaging on the pipeline section, imaging through the optimized TSVD regularization method, and processing the imaging image through SURF and binarization Obtain solid phase holdup and liquid phase holdup. By adopting the phase holdup measurement method of gas-liquid-solid three-phase fluid separation of the present invention, the holdup of each phase can be obtained under the condition of non-destructive testing, and the accuracy of measuring holdup of each phase in a strong interference environment can be improved.
Description
technical field [0001] The invention relates to a gas-liquid-solid three-phase flow separation phase holdup measurement method based on ultrasonic tomography, in particular to a gas-liquid-solid three-phase flow separation phase holdup measurement method. Background technique [0002] The "phase" in multiphase flow is defined as the existence form of substances, that is, gaseous, liquid or solid, so multiphase flow is a fluid in which two or more "phases" flow simultaneously and have a clear interface. Sometimes, multiphase flow is also referred to as "multicomponent flow", however the two are different. The latter refers to the simultaneous flow of multiple substances with different chemical properties in the fluid. For example, the mixture of steam and water is a single-component two-phase flow, while air and water are called two-component flow; the oil-water mixed flow in liquid / liquid two-phase flow belongs to two-component flow, but it is a single "liquid flow". Howeve...
