Provided that the initial kinetic-energy input is sufficient, the flow develops a turbulent mixing zone through non-linear interactions of the material interface perturbations [13], [17]. ISBI was intensively studied over the last decades. The first detailed experimental investigations were performed ...
Geometry effectNumerical simulationThe shock-induced ignition and detonation wave propagation in reactive elliptic premixed bubbles are numerically studied.Close attention is paid to the bubble geometry effect on the ignition pattern and the ensuing bubble behavior.Five elliptic bubbles with different aspect...
We derive a number of diagnostics for observations and laboratory experiments of shock-bubble interactions, like the shock-vortex standoff distance, which can be used to derive lower limits on the Mach number. The differential rotation of the vortex field leads to viscous dissipation, which is ...
a cylindrical bubble embedded with hydrogen surrounded by air was accelerated by a shock. The evolution can be divided into the lobe-emergence stage, the back-lobe suction stage, and the equilibrium stage. Based on the inhomogeneity

As a result, the shock wave-bubble interactions [78] (including both the incident and reflected shock waves, as well as the Schmidt head waves shown in Fig. 10a and 10d) and successively boosted collapses are produced at multiple spots, releasing acoustic energies locally in close proximity to...

shockbubble interactionsA high-resolution method is developed to capture the material interfaces of compressible two-fluid flows in multiple dimensions. A fluid mixture model system with single velocity and pressure is used, and viscous effect can also be taken into account. A consistent thermodynamic...
shock-bubble interactionhomogeneous modelThis paper presents a numerical study of the shock-bubble interaction of a compressible two-phase flows. The investigations such flows are performed using an inviscid one-fluid solver in the presence of shock wave and strong rarefaction waves similar to ...
A Free-Lagrange CFD code is used to model in axisymmetric form the near-field interactions between a lithotripter shock wave and a single spherical air bubble near a rigid boundary in water. The asymmetric collapse of the bubble is induced by the relatively strong incident lithotripter shock wave...
