Energy partition at the collapse of spherical cavitation bubbles.
Spherically collapsing cavitation bubbles produce a shock wave followed by a rebound bubble. Here we present a systematic investigation of the energy partition between the rebound and the shock. Highly spherical cavitation bubbles are produced in microgravity, which suppresses the buoyant pressure gradient that otherwise deteriorates the sphericity of the bubbles. We measure the radius of the r...
متن کاملMultifragmentation of non-spherical nuclei
In studying the multifragmentation process, a large range of incident energies, changing by about four orders in magnitude, was covered and various types of projectiles, from proton till heaviest available ions, were probed. The reaction mechanism is often considered in terms of two-step scenario where the first, off-equilibrium and dynamical step results in the formation of thermalized source ...
متن کاملSquishy non-spherical hydrogel microparticles.
Recent advances in the synthesis of polymeric colloids have opened the doors to new advanced materials. There is strong interest in using these new techniques to produce particles that mimic and/or interact with biological systems. An important characteristic of biological systems that has not yet been exploited in synthetic polymeric colloids is their wide range of deformability. A canonical e...
متن کاملllenges in packing problems: from spherical to non-spherical particles
HIGHLIGHT Adrian Baule and Hernán A. Makse Fundamental challenges in packing problems: from spherical to non-spherical particles Random packings of objects of a particular shape are ubiquitous in science and engineering. However, such jammed matter states have eluded any systematic theoretical treatment due to the strong positional and orientational correlations involved. In recent years progre...
متن کاملNon - spherical core collapse supernovae
Two-dimensional simulations of strongly anisotropic supernova explosions of a nonrotating 15 M ⊙ blue supergiant progenitor are presented, which follow the hydrodynamic evolution from times shortly after shock formation until hours later. It is shown that explosions which around the time of shock revival are dominated by low-order unstable modes (i.e. by a superposition of the l = 2 and l = 1 m...
