Spatiotemporal Dynamics of Hydrogen Plasma Smelting Reduction of iron ore: A Multi-Species Diagnostic Approach
Ram Krushna Mohanta, Kai Lopez, Sai Vishnu Korsipati +4
Plasma-based mineral-processing routes, such as hydrogen plasma smelting reduction (HPSR), which converts iron-ore fines directly to liquid metal in a single scalable step are comm…
Vidyut3d: a GPU accelerated fluid solver for non-equilibrium plasmas on adaptive grids
Hariswaran Sitaraman, Nicholas Deak, Taaresh Taneja
We present the numerical methods, programming methodology, verification, and performance assessment of a non-equilibrium plasma fluid solver that can effectively utilize current an…
Triboplasma assisted chemical conversion in granular systems: a semi-analytic model
Hariswaran Sitaraman, Sankaran Sundaresan
We present a semi-analytic model for a novel plasma-assisted chemical conversion pathway using triboplasmas generated in granular flows. Triboelectric charge relaxation is a well k…
Bayesian calibration of bubble size dynamics applied to CO2 gas fermenters
Malik Hassanaly, John M. Parra-Alvarez, Mohammad J. Rahimi +2
To accelerate the scale-up of gaseous CO2 fermentation reactors, computational models need to predict gas-to-liquid mass transfer which requires capturing the bubble size dynamics,…
Adaptive Computing for Scale-up Problems
Kevin Patrick Griffin, Hilary Egan, Marc T. Henry de Frahan +11
Adaptive Computing is an application-agnostic outer loop framework to strategically deploy simulations and experiments to guide decision making for scale-up analysis. Resources are…
Surface chemistry models for GaAs epitaxial growth and hydride cracking using reacting flow simulations
Malik Hassanaly, Hariswaran Sitaraman, Kevin L. Schulte +5
Hydride Vapor Phase Epitaxy (HVPE) is a promising technology that can aid in the cost reduction of III-V materials and devices manufacturing, particularly high-efficiency solar cel…
Performance comparison of CFD-DEM solver MFiX-Exa, on GPUs and CPUs
Shandong Lao, Aaron Holt, Deepthi Vaidhynathan +3
We present computational performance comparisons of gas-solid simulations performed on current CPU and GPU architectures using MFiX Exa, a CFD-DEM solver that leverages hybrid CPU+…
An adaptive timestepping methodology for particle advance in coupled CFD-DEM simulations
Hariswaran Sitaraman, Ray Grout
An adpative integration technique for time advancement of particle motion in the context of coupled computational fluid dynamics (CFD) - discrete element method (DEM) simulations i…
