Article Description

Utilizing CO 2 jets for rock breaking in energy exploration provides a dual benefit of enhancing recovery rate and facilitating permanent CO 2 sequestration. The novel technology of multi-hole flashing CO 2 jets shows promise in creating high-quality drilling holes, with a better understanding of jet evolution leading to improved breaking efficiency. In this study, the morphologies of multi-hole flashing liquid CO 2 jets were captured using the diffusive back-illuminated method. However, differences in intensity contrast between the main jet and the background, along with light steer effects induced by severe phase transitions, posed challenges in applying uniform thresholds or adjustment parameters for data comparison. To address this issue and ensure the acquisition of high-credibility data, both static and dynamic background-based methods were employed to mitigate contrast level differences between the main jet and the background. The study also analyzed the impact of image processing on jet width sensitivity. The gradient-based method allows for boundary identification based on uniform criteria regardless of contrast levels between the jet and the background, making it suitable for determining the jet width of multi-hole liquid CO 2 flashing jets.
