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...
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 ...

Abstract Two-dimensional shock–bubble interaction is an analogy of the steady three-dimensional jet flow in a scramjet. On the basis of Navier–Stokes simulations, a cylindrical bubble embedded with hydrogen surrounded by air was accelerated by a shock. The evolution can be divided into the lobe...
Experiments were performed for slow/fast (air-helium) and fast/slow (air-SF6) interactions. Full numerical simulations were conducted resulting in good agreement. From the results, it is seen that in both cases, according to the proposed scaling, the vortex ring velocity is bubble radius ...

Also, the interactions between an air bubble and a plane shock wave in mercury in the vicinity of a glass wall are simulated. The mercury and glass are evaluated by using the stiffened gas equations. The motions of three phases for air, mercury, and glass are solved directly coupling the ...
The behavior of a collapsing bubble is influenced by complex interactions with other bubbles [278–280]. Adhikari and colleagues [281] published a molecular dynamics study on membrane poration by shock wave-induced nanobubble collapse. Their results revealed that, after shock wave passage, nanojets ...
