Experimental investigation reveals jetting and collapse dynamics of bubbles in water under shock waves, suggesting new insights for high-energy-density systems.
Key Points
The aim is to investigate shock wave and bubble interactions in water, focusing on their dynamics and outcomes.
Utilized ultra-high-speed x-ray phase contrast imaging to capture interactions.
Conducted experiments with a micrometric nitrogen bubble and a planar shock wave.
Characterized shock wave at Mach number M=1.24 and peak pressure of 0.57 GPa.
Measured time-varying bubble size and bubble collapse jet speed.
Documented the detailed dynamics of shock-induced bubble collapse and jetting.
Provided critical benchmark data for validating numerical simulations.
Quantified jet speed produced during bubble collapse and time evolution of the shock wave front.
