Embodiment Construction

[0009] Select the corresponding ultrasonic transducer according to parameters such as multiphase flow density and concentration, and install the transducer on the ultrasonic array detection device described in step 1. All ultrasonic transducers that can be used for replacement are water-immersed transducers device. The multiphase flow is located in the sample cell. figure 1 It is a schematic diagram of the detection device, and each part is: sample pool, high-frequency ultrasonic transducer, high-frequency ultrasonic transceiver card, data processing device, etc.

[0010] Acoustic impedance of multiphase flow:

[0011] Z = ρc (1)

[0012] In the formula: ρ——density of multiphase fluid;

[0013] c—the propagation speed of ultrasonic wave in multiphase fluid.

[0014] The density of the multiphase flow can be obtained from the measured impedance and sound velocity. When the ultrasonic wave is vertically incident on the multiphase flow from one side of the measurement sample...

Abstract

The invention aims to provide an ultrasonic array detection method for multi-phase liquid density and concentration. The method is applied to detecting the properties of density and concentration of multi-phase liquid in real time, and can be widely applied to a plurality of fields such as the flight and aviation field, the industrial machinery field, the chemicals field, the water conservation field and the biomedicine field and the like. The ultrasonic array detection method for the multi-phase liquid density and the concentration comprises the following steps: vertically emitting an ultrasonic wave beam into a multi-phase liquid; receiving reflected or projected ultrasonic signals from the inside of the multi-phase liquid through an ultrasonic transducer array; and calculating the acoustic impedance of the multi-phase liquid and the spreading speed of the sound wave in the multi-phase liquid, as well as obtaining and displaying the property parameters of the multi-phase liquid in real time such as density and concentration and the like.

Description

1. Technical field [0001] The invention belongs to the technical field of nondestructive testing, specifically relates to multiphase fluid and ultrasonic transducer array detection technology, and is a method for real-time and high-precision detection of characteristics such as density and concentration of multiphase fluid. 2. Background technology [0002] Multiphase fluid density and concentration ultrasonic array detection method is a non-destructive testing technology that can detect the density and concentration of multiphase fluid in real time. It uses high-frequency ultrasonic waves to interact with the measured multiphase fluid to obtain the concentration, density, etc. The characteristic parameters are widely used in many fields such as aerospace, industrial machinery, biomedicine, chemical industry and hydraulics, such as the concentration of mud particles during oil drilling and the content of gas and water in oil-gas-water three-phase flow in oil wells , the cont...
