Shell to shell energy transfer in MHD, Part II: Kinematic dynamo

open access: yes, 2005
We study the transfer of energy between different scales for forced three-dimensional MHD turbulent flows in the kinematic dynamo regime. Two different forces are examined: a non-helical Taylor Green flow with magnetic Prandtl number P_M=0.4, and a ...

Phoretic self-propulsion at finite P\'eclet numbers [PDF]

open access: yes, 2014
Phoretic self-propulsion is a unique example of force- and torque-free motion on small scales. The classical framework describing the flow field around a particle swimming by self-diffusiophoresis neglects the advection of the solute field by the flow ...

On the multispacecraft determination of periodic surface wave phase speeds and wavelengths [PDF]

open access: yes, 2010
Observations of surface waves on the magnetopause indicate a wide range of phase velocities and wavelengths. Their multispacecraft analysis allows a more precise determination of wave characteristics than ever before and reveal shortcomings of ...

The disappearance of viscous and laminar wakes in complex flows [PDF]

open access: yes, 2002
The singular effects of steady large-scale external strain on the viscous wake generated by a rigid body and the overall flow field are analysed. In an accelerating flow strained at a positive rate, the vorticity field is annihilated owing to positive ...

Azimuthally symmetric MHD and two-fluid equilibria with arbitrary flows [PDF]

open access: yes, 2000
Magnetohydrodynamic (MHD) and two-fluid quasi-neutral equilibria with azimuthal symmetry, gravity and arbitrary ratios of (nonrelativistic) flow speed to acoustic and Alfven speeds are investigated.

Analysis on Flow Field Characteristics and Barite Recovery Efficiency of Drilling Centrifuge

open access: yesShiyou jixie, 2022
Aiming at the recovery efficiency of barite in high density drilling fluid of ultra-deep wells, the drilling fluid was considered as a liquid-solid-solid fluid model to analyze the transient change process of flow field in centrifuge and the influence of
