This paper describes numerical implementation of a newly developed hybrid model, T-bbb/7'-TAB, into an existing computational fluid dynamics (CFD) program for primary and secondary breakup simulation of liquid jet atomization. This model extend two widely used models, the Kelvin-Helmholtz (KH) instability of Reitz (blob model) and the Taylor-Analogy-Breakup (TAB) secondary droplet breakup by O'...

Recent developments on the understanding of low energy reactions are highlighted. Emphasis is given to the CDCC framework where the breakup channels of the projectile are included explicitly. Properties of the breakup couplings are presented. Comments are given with regard to the separation between the nuclear and the Coulomb contributions to breakup cross sections as well as the dependence on ...

Quantitative application of digital in-line holography (DIH) to characterize multiphase fragmentation is demonstrated. DIH is applied to record sequential holograms of the breakup of an ethanol droplet in an aerodynamic flow field. Various stages of the breakup process are recorded, including deformation, bag growth, bag breakup, and rim breakup. A recently proposed hybrid method is applied to ...

Frozen rivers in the Arctic serve as critical highways because of the lack of roads; therefore, it is important to understand the key mechanisms that control the timing of river ice breakup. The relationships between springtime Interior Alaska river ice breakup date and the large-scale climate are investigated for the Yukon, Tanana, Kuskokwim, and Chena Rivers for the 1949–2008 period. The most...

In collisions between two nuclei the breakup of the projectile into two or more fragments is often a strong reaction channel, which affects not only the imaginary part but also the real part of the corresponding optical potential. This leads to a dynamical polarization potential (DPP) which has to be added to the real potential calculated by the double folding (DFM) models (see eg. a recent rev...

A classical dynamical model that treats breakup stochastically is presented for low energy reactions of weakly bound nuclei. The three-dimensional model allows a consistent calculation of breakup, incomplete, and complete fusion cross sections. The model is assessed by comparing the breakup observables with continuum discretized coupled-channel quantum mechanical predictions, which are found to...

With the discovery of halo nuclei, and recent intensive development of radioactive ion beams (RIBs) around the world, there is renewed interest in studying interaction of weakly-bound light nuclei as a basis for understanding interactions of halo nuclei and RIBs. Using a novel experimental approach [1], reactions of the weakly–bound nuclei Be and Li with heavy targets consistently showed suppre...

The problem of turbulent liquid breakup refers to the disintegration of a turbulent liquid jet owing to competing effects of aerodynamic forces, surface tension forces and turbulence when injected into a stationary or moving ambient gas. Owing to the difficulty in predictively modeling breakup of turbulent liquid jets, this phenomenon is considered to be an unsolved problem in the field of flui...

Abstract We calculate the nuclear induced breakup of Be and B using a more realistic treatment of the diffraction and stripping processes than in previous work. The breakup is treated in the eikonal approximation with a profile function calculated from a realistic optical potential at low energies and from free nucleon-nucleon cross sections at high energies. This treatment gives a good descrip...

The breakup of 11Be on carbon and lead targets around 70 MeV/nucleon is investigated within a semiclassical framework. The role of the 5 2 + resonance is analyzed in both cases. It induces a narrow peak in the nuclear-induced breakup cross section, while its effect on Coulomb breakup is small. The nuclear interactions between the projectile and the target is responsible for the transition towar...
