Axisymmetry of mantle aspherical structures
Geophysical Research Letters, 1995 Recent seismic tomographic models have revealed broad, low velocity anomalies in the lower mantle beneath Africa and the central Pacific that correspond to the poles of the surface geotectonic reference network. We test the hypothesis that the tomographic models are axisymmetrical with respect to axes passing near the geotectonic poles. The symmetry is

Electronic 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.

AIP 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 ...

Planetary nebulae that cannot be explained by binary systems
, 2017 We examine the images of hundreds of planetary nebulae (PNe) and find that for about one in six PNe the morphology is too `messy' to be accounted for by models of stellar binary interaction.

Three-dimensional solutions for the geostrophic flow in the Earth's core [PDF]
, 2018 In his seminal work, Taylor (1963) argued that the geophysically relevant limit for dynamo action within the outer core is one of negligibly small inertia and viscosity in the magnetohydrodynamic equations. Within this limit, he showed the existence of a

Journal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.Abstract Mesoscale eddies pulsate, tilt with depth, and deform, but these processes are rarely resolved together from multi‐depth Lagrangian observations. We analyze a long‐lived intrathermocline anticyclonic eddy in the Canary Eddy Corridor using four drifters spanning 15–150 m and a novel, position‐only ellipse‐fitting method based on axis‐aligned ...

Solar surface rotation: N-S asymmetry and recent speed-up
, 2015 Context. The relation between solar surface rotation and sunspot activity still remains open. Sunspot activity has dramatically reduced in solar cycle 24 and several solar activity indices and flux measurements experienced unprecedentedly low levels ...

Large contact angle hysteresis enhances post‐impact droplet oscillations
Droplet, Volume 5, Issue 1, January 2026.Contact angle hysteresis (CAH) sustains high‐order droplet oscillations after impact by enabling nonlinear energy transfer between modes, leading to persistent modulated shape dynamics. Abstract Droplet impact on solid surfaces plays a critical role in a wide range of applications, including inkjet printing, spray cooling, surface coatings, and ...

Support Structure Modelling in Actuator Line Method Large Eddy Simulations of Wind Turbine Wakes
Wind Energy, Volume 29, Issue 1, January 2026.ABSTRACT While advancements in the prediction of wind turbine loads and wakes within the actuator line method large eddy simulation (ALM‐LES) framework have been an active research topic in recent years, the modelling of the tower and nacelle has received comparatively less attention.
