Neural-network surrogate predicts particle hydrodynamic responses accurately
—
in MechanicsWhat the study found A data-driven surrogate framework was developed to estimate hydrodynamic responses of rigid, non-spherical particles in Stokes flow, including the stresslet, angular velocity, and, for helicoidal particles, chiral thrust. The surrogate was trained on data generated by a validated boundary element method and was tested across random orientations and flow types. Why…
Rarefaction weakens electromagnetic flow control in hypersonic plasma
—
in EngineeringWhat the study found Rarefaction effects weaken the influence of electromagnetic control in hypersonic flow around a hemisphere. The study also indicates that the unified gas-kinetic wave-particle (UGKWP) method can model this kind of electromagnetic flow across near-continuum to rarefied conditions. Why the authors say this matters The authors conclude that the results highlight UGKWP's…
Full-resolution model reproduces key MSRE flow and neutron data
Full-resolution multiphysics simulation of the Molten Salt Reactor Experiment couples neutronics with thermal-hydraulics to reproduce experimental behavior and reveal three-dimensional flow.
GPU-optimized PLUTO code shows preliminary performance results
gPLUTO is a GPU-optimized implementation of the PLUTO code for solving magnetohydrodynamic equations. Preliminary results demonstrate performance viability on pre-exascale parallel architectures.
