Hybrid-Delta Tracking on a Structured Mesh in MCATK
J. P. Morgan, Travis J. Trahan, Timothy P. Burke +2
Monte Carlo Application Toolkit (MCATK) commonly uses surface tracking on a structured mesh to compute scalar fluxes. In this mode, higher fidelity requires more mesh cells and iso…
Development of MC/DC: a performant, scalable, and portable Python-based Monte Carlo neutron transport code
Ilham Variansyah, J. P. Morgan, Jordan Northrop +2
We discuss the current development of MC/DC (Monte Carlo Dynamic Code). MC/DC is primarily designed to serve as an exploratory Python-based MC transport code. However, it seeks to…
Exploring One-Cell Inversion Method for Transient Transport on GPU
J. P. Morgan, Ilham Variansyah, Todd S. Palmer +1
To find deterministic solutions to the transient neutron transport equation, iterative schemes are typically used to treat the scattering (and fission) source terms. We explo…
Smoldering combustion in cellulose and hemicellulose mixtures: Examining the roles of density, fuel composition, oxygen concentration, and moisture content
W. Jayani Jayasuriya, Tejas Chandrashekhar Mulky, Kyle E. Niemeyer
Smoldering combustion plays a key role in wildfires in forests, grasslands, and peatlands due to its common occurrence in porous fuels like peat and duff. As a consequence, underst…
Accelerating reactive-flow simulations using vectorized chemistry integration
Nicholas J. Curtis, Kyle E. Niemeyer, Chih-Jen Sung
The high cost of chemistry integration is a significant computational bottleneck for realistic reactive-flow simulations using operator splitting. Here we present a methodology to…
Assessing diffusion model impacts on enstrophy and flame structure in turbulent lean premixed flames
Aaron J. Fillo, Peter E. Hamlington, Kyle E. Niemeyer
Diffusive transport of mass occurs at small scales in turbulent premixed flames. As a result, multicomponent mass diffusion, which is often neglected in direct numerical simulation…
