摘      要：Ultrasound technology has been recognized as the mainstream approach for the identification of gasliquid two-phase flow patterns,which holds great value in engineering ***,commercial rigid probes are bulky,limiting their adaptability to curved ***,we propose a strategy for autonomous identification of flow patterns based on flexible ultrasound array and machine *** array features high-performance 1–3 piezoelectric composite material,stretchable serpentine wires,soft Eco-flex layers and a polydimethylsiloxane(PDMS)adhesive *** resulting ultrasound array exhibits excellent electromechanical characteristics and offers a large stretchability for an intimate interfacial contact to curved surface without the need of ultrasound coupling *** demonstrated that the flexible ultrasound array combined with machine learning can accurately identify gas-liquid two-phase flow patterns,in a circular *** work presents an effective tool for recognizing gas-liquid two-phase flow patterns,offering engineering opportunities in petroleum extraction and natural gas transportation.
