AI Technical Summary
In existing technologies, the freezing process causes the liquid phase water in the fluid inclusion to solidify into ice, destroying the physical meaning of the original gas-liquid ratio and making it impossible to accurately measure the gas-liquid ratio.
A standing wave sound field was generated by combining high-frequency acoustic waves with a piezoelectric transducer array and a holographic acoustic lens to lock the bubbles in the inclusion. The gas-liquid phase composition was verified by Raman spectroscopy and corrected by three-dimensional CT scanning, and the gas-liquid ratio was calculated.
It can accurately locate air bubbles without freezing, avoid liquid phase solidification, ensure data reliability, reduce volume error, and improve the accuracy of gas-liquid ratio measurement.
