High-Throughput Exploration of Refractory High-Entropy Alloys for Strength and Plasticity
Stephen A. Giles, Hugh Shortt, Peter K. Liaw +1
Refractory high-entropy alloys (RHEAs) are compositionally complex materials which have been demonstrated to have the potential for exceptional strength at high operating temperatu…
Large Field-of-View Thermal Imaging via All-Silicon Meta-Optics
Anna Wirth-Singh, Johannes E. Fröch, Zheyi Han +6
A broad range of imaging and sensing technologies in the infrared require large Field-of-View (FoV) operation. To achieve this, traditional refractive systems often employ multiple…
Ionization waves (striations) in low-current DC discharges in noble gases obtained with a hybrid kinetic-fluid model
Vladimir I. Kolobov, Robert R. Arslanbekov
A hybrid kinetic-fluid model is used to study ionization waves (striations) in a low-current plasma column of DC discharges in noble gases. Coupled solutions of a kinetic equation…
A self-consistent hybrid model of kinetic striations in low-current Argon discharges
Vladimir I. Kolobov, Juan Alonso Guzman, Robert R. Arslanbekov
A self-consistent hybrid model of standing and moving striations was developed for low-current DC discharges in noble gases. We introduced the concept of surface diffusion in phase…
Electron kinetics in standing and moving striations in argon gas
Dmitry Levko
The electron kinetics in moving and standing striations in direct current and radio-frequency discharges is studied. The discharge current is such that the thermalizing electron-el…
Plasma Stratification in Radio-Frequency Discharges of Noble Gases
Vladimir I Kolobov, Robert R Arslanbekov, Dmitry Levko +1
We conducted experimental studies and computer simulations of standing striations in capacitive coupled plasma in Argon gas. Standing striations were observed at frequencies 3.6, 8…
Electron Groups in Solar Wind and Gas Discharge Plasmas
Vladimir Kolobov, Robert Arslanbekov, Dmitry Levko
The formation of electron groups is a common phenomenon in gas discharges and space plasmas. We describe similarities between electron kinetics in solar wind, cathode region of glo…
Laser-generated plasmas in length scales relevant for thin film growth and processing: simulation and experiment
Sumner B. Harris, Jacob H. Paiste, Tharon J. Holdsworth +2
In pulsed laser deposition, thin film growth is mediated by a laser-generated plasma, whose properties are critical for controlling the film microstructure. The advent of 2D materi…
Design and Evaluation of Torque Compensation Controllers for a Lower Extremity Exoskeleton
Xianlian Zhou, Xinyu Chen
In this paper, we present an integrated human-in-the-loop simulation paradigm for the design and evaluation of a lower extremity exoskeleton that is elastically strapped onto human…
Boltzmann-Fokker-Planck Kinetic Solver with Adaptive Mesh in Phase Space
Vladimir Kolobov, Robert Arslanbekov, Dmitry Levko
We describe the implementation of kinetic solvers in 1d2v phase space using adaptive Cartesian mesh. Spherical coordinates in velocity space are used to simplify the Lorentz and Fo…
Kinetic Solvers with Adaptive Mesh in Phase Space for Low-Temperature Plasmas
Vladimir Kolobov, Robert Arslanbekov, Dmitry Levko
We describe the implementation of 1d1v and 1d2v Vlasov and Fokker-Planck kinetic solvers with adaptive mesh refinement in phase space (AMPS) and coupling these kinetic solvers to P…
Adaptive Kinetic-Fluid Models for Expanding Plasmas
Robert R. Arslanbekov, Vladimir I. Kolobov
We describe gas dynamic and plasma effects for transient plasma jets under different conditions. Our Unified Flow Solver (UFS) is evaluated for simulations of mixed continuum-raref…

A discontinuous Galerkin time-domain (DGTD) method based on dynamically adaptive Cartesian meshes (ACM) is developed for a full-wave analysis of electromagnetic fields in dispersiv…
Adaptive Kinetic-Fluid Solvers for Heterogeneous Computing Architectures
Sergey Zabelok, Robert Arslanbekov, Vladimir Kolobov
We show feasibility and benefits of porting an adaptive multi-scale kinetic-fluid code to CPU-GPU systems. Challenges are due to the irregular data access for adaptive Cartesian me…
Kinetic Solvers with Adaptive Mesh in Phase Space
Robert R. Arslanbekov, Vladimir I. Kolobov, Anna A. Frolova
An Adaptive Mesh in Phase Space (AMPS) methodology has been developed for solving multi-dimensional kinetic equations by the discrete velocity method. A Cartesian mesh for both con…
