Abstract Content of image described in text. Cavitation bubbles collapsing near capillary exits can generate fast microjets that penetrate into the channel and promote fluid exchange. Here, we combine high-speed imaging and axisymmetric compressible volume-of-fluid simulations to study laser-induced cavitation bubbles...

Abstract Content of image described in text. The shear flow induced by a jetting cavitation bubble within grooved structures is systematically investigated using a three-dimensional compressible volume-of-fluid (VoF) solver combined with ultra-high-speed photography of one million frames per second (fps). The structure...

Abstract Content of image described in text. Direct numerical simulations are performed to investigate the effects of discontinuous slip boundaries comprising alternating slip regions and transverse no-slip stripes on turbulent channel flow and drag reduction mechanisms. Compared with a continuous slip boundary with th...

Abstract Content of image described in text. This study experimentally investigates the interfacial instabilities and thermo-hydrodynamic mechanisms of supercavities ventilated by high-temperature condensable vapour. Using high-speed imaging with an AI-based segmentation model, we establish a flow regime map that delin...
