Nonisothermal conservative phase-field model for electric breakdown process

Conservative phase-field lattice Boltzmann model for interface tracking equation.

Based on the phase-field theory, we propose a conservative lattice Boltzmann method to track the interface between two different fluids. The presented model recovers the conservative phase-field equation and conserves mass locally and globally. Two entirely different approaches are used to calculate the gradient of the phase field, which is needed in computation of the normal to the interface. ...

Electric field breakdown in single molecule junctions.

Here we study the stability and rupture of molecular junctions under high voltage bias at the single molecule/single bond level using the scanning tunneling microscope-based break-junction technique. We synthesize carbon-, silicon-, and germanium-based molecular wires terminated by aurophilic linker groups and study how the molecular backbone and linker group affect the probability of voltage-i...

Phase field analysis of Eutectic Breakdown

In this paper an isotropic multi-phase-field model is extended to include the effects of anisotropy and the spontaneous nucleation of an absent phase. This model is derived and compared against a published single phase model. Results from this model are compared against results from other multi-phase models, additionally this model is used to examine the break down of a regular two dimensional ...

Electric Field Breakdown Characteristics of Carbon-based Ion Optics

Ion thrusters are being designed for long-term operation at power, specific impulse, and thrust levels of up to 29 kW, 7000 seconds, and 0.64 N, respectively. The total propellant throughput goal of these thrusters is nearly 100 kg/kW, which corresponds to ~100 khr of operation. Carbon-based grids have been chosen as the baseline design to achieve this propellant throughput and life time goal. ...
