Three-dimensional multiphase flow and flow with phase change are simulated using a simplified method of tracking and reconstructing the phase interface. The new level contour reconstruction technique presented here enables front tracking methods to naturally, automatically, and robustly model the merging and breakup of interfaces in three-dimensional flows. The method is designed so that the ph...

A phase-field method is applied to the modeling of flow and breakup of droplets in a T-shaped junction in the hydrodynamic regime where capillary and viscous stresses dominate over inertial forces, which is characteristic of microfluidic devices. The transport equations are solved numerically in the three-dimensional geometry, and the dependence of the droplet breakup on the flow rates, surface...

Inter-firm R&D collaborations through contractual arrangements have become increasingly popular, but in many cases they are broken up without any joint discovery. We provide a rationale for the breakup date in R&D collaboration agreements. More specifically, we consider a research consortium initiated by a firm A with a firm B. B has private information about whether it is committed to the proj...

The $^{8}\mathrm{Li}+^{58}\mathrm{Ni}$ collision is investigated at 23.9, 26.1, 28.7, and 30 MeV bombarding energies. Quasielastic angular distributions the singles $^{7}\mathrm{Li}$ energy are presented. Coupled-reaction channels (CRC) calculations, which include coupling of elastic channel to $^{59}\mathrm{Ni}=^{58}\mathrm{Ni}\phantom{\rule{0.16em}{0ex}}+\phantom{\rule{0.16em}{0ex}}n$ states ...

A temporal stability analysis was carried out for a planar liquid sheet sandwiched between two gas streams moving with unequal velocities. Perturbation analysis was carried out up to second order using the initial amplitude of disturbance of the liquid sheet as the perturbation parameter. Both para-sinuous and para-varicose modes were investigated to determine the dominant break-up mechanism. T...

The North Atlantic Igneous Province (NAIP) has been the focus of numerous studies. However, a systematic integrated methodology to assess NAIP, so far lacking. For this purpose, synclinal oceanic rift approach is developed from stratigraphic record. Mechanisms are addressed combining trace element and seismic velocity data as proxy for excess mantle potential temperature (ΔTp), using simple mel...

Cavitation and turbulence in a diesel injector nozzle has a great effect on the development and primary breakup of spray. However, the mechanism of the cavitation flow inside the nozzle and its influence on spray characteristics have not been clearly known yet because of the internal nozzle flow complexities. In this paper, a comprehensive numerical simulation is carried out to study the intern...
