Neutron-deuteron breakup and quasielastic scattering
Quasielastic scattering and deuteron breakup in the 200 MeV region is studied by impinging a pulsed neutron beam on a deuterium target at the Weapons Neutron Research facility at the Los Alamos Neutron Science Center. The scattered neutrons from the d(n,np)n reaction are detected by a wall of …

Supercontinental Inheritance and its Influence on Supercontinental Breakup: The Central Atlantic Magmatic Province and the Breakup of Pangea
… igneous province (LIP) that coincides with the breakup of the supercontinent Pangea. Major and trace element data, Sr-Nd-Pb radiogenic isotopes, and high-precision olivine chemistry were collected on primitive CAMP dikes from Virginia (VA). These new samples were used in conjunction with a …

Capillary breakup of Discontinuously Rate Thickening Suspensions
… Rate Thickening Suspensions (DRTS) in capillary breakup, where a thin suspension filament breaks up under the action of surface tension forces. We performed experiments with 55% by weight suspension of cornstarch in glycerol. To minimize the effect of gravity on the experiments, we developed a …

Charged-particle tracking for neutron-deuteron breakup
… measure the energy of protons scattered in the breakup process d(n, np)n. The nd breakup experiment is performed at the Weapons Neutron Research facilities at Los Alamos Neutron Science Center. In order to fully define breakup kinematics for the stationary deuterium target, the following are …

Large eddy simulation of primary liquid-sheet breakup
… numerical techniques to model the primary breakup of liquid fuel into droplets. Based on this and keeping in mind the requirements of the industry, our modelling strategy led to the generation of a mass-conservative method for efficient atomisation modelling on unstructured meshes. This …

Breakup and coalescence in turbulent two-phase flows
… the bubbles or drops of a dispersion to undergo breakup and coalescence, and the resulting changes in the dispersion may significantly affect the engineering process under consideration. For this reason, many researchers have studied breakup and coalescence in turbulent two phase flows. Models …

Experimental Investigation of Jet Breakup at Low Weber Number
… is presented in this thesis. The process of breakup of the liquid jet was captured using a real-time image processing high-speed digital camera system. In order to understand the influence of inertial, surface tension, and viscous forces on the process of breakup, a range of Weber numbers …

Debris Propagation due to a Space Vehicle Breakup at High Altitudes
… containing falling debris due to a space vehicle breakup. A precise computation of propagation of debris to the ground is not practical for many reasons. There is insufficient knowledge of the initial state vector, ambient wind conditions and the key parameters including the ballistic coecients. …

Modelling the controls on melt generation during continental extension and breakup
… melt generated during continental extension and breakup.<br/>The central aim is to understand how melting affects the rifting of continents, especially<br/>in the North Atlantic. In order to understand the enigmatic melt production observed<br/>around the North Atlantic various tools are …

Modeling of surges caused by the release of breakup ice jams
… crossings. The current understanding of the breakup ice jam phenomena is insufficient and therefore the state-of-the-art is not well advanced. There is an urgent need to improve it. The primary objective of this study is to identify and determine through laboratory as well as numerical …

The neutron-deutron breakup cross section between 8 and 22 MeV
The n-d breakup cross section has been measured at eleven energies. between 8 and 22 MeV by integrating the energy distributions of breakup protons in a deuterated scintillator. The breakup protons were separated from the recoil deuterons by pulse shape discrimination. A comparison of these …

Methods for the direct simulation of nanoscale film breakup and contact angles
… initial liquid geometry is presented, the breakup of which requires direct numerical simulation in order to explain the experimental behavior. A parameter study of this geometry demonstrates that it offers a rich variety of dynamics; the breakup of the geometry is found to result in …

The post-breakup evolution of the western Indian high-elevation passive margin
The tectonic development of the Western Indian high-elevation passive margin is complex. At least two major rifting events (India/Madagascar and India/Seychelles) and a major hotspot (The Reunion plume) are believed to have been instrumental in the formation and development of the margin. However, …
