Vibration analysis of rotating rings with complex support stiffnesses

open access: yesMATEC Web of Conferences, 2018
Vibration characteristics of rotating rings with complex support stiffnesses are studied. The complex stiffnesses of the rotating ring include discrete stiffnesses and partially distributed stiffnesses. The governing equations are established by Hamilton’

Modeling non-axisymmetry in the DIII-D small angle slot divertor using EMC3-EIRENE

open access: yesNuclear Materials and Energy, 2018
The 3D edge transport code EMC3-EIRENE is used to evaluate the effects of non-axisymmetric misalignment of the small angle slot (SAS) divertor on DIII-D.

Protoneutron Star Convection Simulated with a New General Relativistic Boltzmann Neutrino Radiation Hydrodynamics Code

open access: yesThe Astrophysical Journal, 2023
We investigate protoneutron star (PNS) convection using our newly developed general relativistic Boltzmann neutrino radiation hydrodynamics code. This is a pilot study for more comprehensive investigations later. As such, we take a snapshot of a PNS at 2.

Boundary‐Only Weak Deflection by Regular Black Holes, Black‐Bounces, Wormholes, and Static Quadrupolar Spacetimes

open access: yesFortschritte der Physik, Volume 74, Issue 8, August 2026.
ABSTRACT We apply the boundary‐only isothermal formulation of finite‐distance weak gravitational deflection to regular black holes, black‐bounces, traversable wormholes, non‐asymptotically flat backgrounds, and static quadrupolar spacetimes. The methodological advance is not a new value for a known bending angle.

Existence of axisymmetric weak solutions of the 3-D Euler equations for near-vortex-sheet initial data

open access: yesElectronic Journal of Differential Equations, 1998
We study the initial value problem for the 3-D Euler equation when the fluid is inviscid and incompressible, and flows with axisymmetry and without swirl.

Peaking Into Oberon's Past: An Isolated Peak Could Imply the Existence of a Subsurface Ocean or Convecting Ice Shell

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract The Uranian moons, last visited in 1986 by Voyager 2, remain an intriguing yet under‐explored set of targets. Understanding the thermal structure and evolution of these moons is key to addressing one of the highest priority goals in planetary science: identifying if any are ocean worlds today or have been in the past. On Oberon, one feature in

Axisymmetric solutions of a two-dimensional nonlinear wave system with a two-constant equation of state

open access: yesElectronic Journal of Differential Equations, 2017
We study a special class of Riemann problem with axisymmetry for two-dimensional nonlinear wave equations with the equation of state $p=A_1\rho^{\gamma_1}+A_2\rho^{\gamma_2 ...

Large-eddy simulation of bluff-body stabilized premixed flames with low-dissipative, structure-preserving convection schemes

open access: yesAIP Advances, 2023
Large eddy simulation (LES) has the potential to predict turbulent combustion phenomena in modern practical combustors. As errors from sub-grid models may be comparable to the numerical errors in the LES approach, mitigating the impact of the numerical ...

Highly Asymmetric Magnetosphere‐Ionosphere‐Thermosphere Coupling at Uranus

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Magnetosphere‐Ionosphere‐Thermosphere (MIT) coupling is widely considered the dominant energy source responsible for maintaining the elevated thermospheric temperatures observed at the giant planets. At Uranus, the strongly tilted and asymmetric magnetic field produces a highly asymmetric magnetospheric configuration that may fundamentally ...
