Discontinuous Piecewise Polynomial Neural Networks
John Loverich
An artificial neural network is presented based on the idea of connections between units that are only active for a specific range of input values and zero outside that range (and…
Modeling radio communication blackout and blackout mitigation in hypersonic vehicles
Madhusudhan Kundrapu, John Loverich, Kristian Beckwith +3
A procedure for the modeling and analysis of radio communication blackout of hypersonic vehicles is presented. The weakly ionized plasma generated around the surface of a hypersoni…
Experimental characterization of the stagnation layer between two obliquely merging supersonic plasma jets
Elizabeth C. Merritt, Auna L. Moser, Scott C. Hsu +2
We present spatially resolved measurements characterizing the stagnation layer between two obliquely merging supersonic plasma jets. Intra-jet collisionality is very high ($λ_{ii}…
Multi-chord fiber-coupled interferometry of supersonic plasma jets and comparisons with synthetic data
Elizabeth C. Merritt, Alan G. Lynn, Mark A. Gilmore +3
A multi-chord fiber-coupled interferometer [Merritt et al., Rev. Sci. Instrum. 83, 033506 (2012)] is being used to make time-resolved density measurements of supersonic argon plasm…
Two-Dimensional Modeling of Ideal Merging Plasma Jets
John Loverich, Ammar Hakim
Idealized merging argon plasma jets are simulated in 2D using both gas dynamic and MHD models. Results indicate that peak pressures of several hundred kilobar can be achieved for h…
A Discontinuous Galerkin Method for Ideal Two-Fluid Plasma Equations
John Loverich, Ammar Hakim, Uri Shumlak
A discontinuous Galerkin method for the ideal 5 moment two-fluid plasma system is presented. The method uses a second or third order discontinuous Galerkin spatial discretization a…
