Laser-assisted guiding of electric discharges around objects [PDF]

open access: yes, 2015
Electric breakdown in air occurs for electric fields exceeding 34 kV/cm and results in a large current surge that propagates along unpredictable trajectories.

Hydrogen eliminator [PDF]

open access: yes, 1972
Vented hydrogen is converted into water by mixing hydrogen with sufficient air to ensure that a flame cannot be maintained and then passing it through a reactor containing palladium catalyst; reaction takes place at relatively low temperature. Device may

Electrode erosion in low power arcjet thrusters [PDF]

open access: yes
Low power arcjet thrusters (0.5 to 3 kW) are currently being considered for North-South station keeping of geosynchronous communication satellites. The erosion mechanisms of cathodes in these thrusters are not well understood.

Numerical solution of degenerate stochastic Kawarada equations via a semi-discretized approach

open access: yes, 2018
The numerical solution of a highly nonlinear two-dimensional degenerate stochastic Kawarada equation is investigated. A semi-discretized approximation in space is comprised on arbitrary nonuniform grids.
