We investigate a reacting shock–bubble interaction through three-dimensional numerical simulations with detailed chemistry. The convex shape of the bubble focuses the shock and generates regions of high pressure and temperature, which are sufficient to ignite the diluted stoichiometric H2O2 gas mixture ...
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-emergence...
The interaction with the incident shock wave leads to the bubble deformation and the formation of liquid jet in the final stage of collapse. Higher impulsive pressure is generated in the mercury when the jet impacts the bubble surface. Also, the interactions between an air bubble and a plane ...

The regular reflection of an air shock wave from a spherical drop of a bubble liquid is studied. In the framework of an extended equilibrium model, the effect of the shock waves on single drops of various shapes and on drop ensembles (drop screens) is numerically investigated. It is shown ...
It will be shown to be related to the interaction of the bubble with the shock wave which is emitted when the collapse is arrested and is successively reflected back by the wall. After the shock/bubble interaction is completed, the bubble starts expanding up to a maximum volume, which is ...
The interaction of a shock wave with a spherical gas inhomogeneity (soap bubble) is experimentally investigated using a high speed camera shadowgraph diagnostic. Negative, close to zero, and positive density jumps across the bubble interface are studied for weak incident shock waves. For each case,...
when cowl shocks affect the shoulder. Meshram et al. [18] studied blunt body double wedge hypersonic flows. They deduced that increasing the deflection angles amplifies the inverse pressure gradients stemming from shock boundary layer interactions, which results in enlarging the separated bubble region...
Mach number effects on shock-bubble interaction An investigation of Mach number effects on the interaction of a shock wave with a cylindrical bubble, is presented. We have conducted simulations with the ... A Bagabir,D Drikakis - 《Shock Waves》 被引量: 95发表: 2001年 A shock model with...
15.3.1.2 SHOCK WAVE AND SPHERICAL BUBBLE INTERACTION: CUMULATIVE JET FORMATION Analysis of the interaction of a plane wave with a spherical bubble allows one to account for two fundamental aspects of the problem: the gas state in the bubble during its collapse behind the shock front, and the ...
