We propose a self-consistent dynamo mechanism for the generation of large-scale magnetic fields in natural objects. Recent computational studies have described the formation of large-scale vortices in rotating turbulent convection. Here we demonstrate that for magnetic Reynolds numbers below the threshold for small-scale dynamo action, such turbulent flows . We present a numerical study of dynamo action in a conducting fluid encased in a metallic spherical shell. Motions in the fluid are driven by differential rotation of the outer metallic shell, which we refer to as ``the wall.'' The two hemispheres of the wall are held in counter-rotation, producing a steady, axisymmetric interior flow consisting of differential rotation and a .

Brummell We have performed numerical simulations of boundary-driven dynamos using a three-dimensional nonlinear magnetohydrodynamical model in a spherical shell geometry. A conducting fluid of magnetic Prandtl number $\mathrm{Pm}=0.01$ is driven into motion by the counter-rotation of the two hemispheric walls. The resulting flow is of von K\'arm\'an type, .
The British Applied Mathematics Colloquium (BAMC) is the largest applied mathematics conference in the UK bringing together students, academics and industry professionals to discuss recent advances within the field. In 2024, BAMC will be held at Newcastle University from Tuesday April 9th to Thursday April 11th 2024 in the Frederick Douglass centre. By analogy with rotating convection, the nonlinear upscale transfer of kinetic energy via the Reynolds stresses might require Reynolds numbers of the order of 100 (Guervilly et al., 2014). This might be achievable in fingering . To cite this article: Stephen J. Mason, Céline Guervilly & Graeme R.

Methods. This is a prospective randomized controlled study. Patients were randomized to receive during 48 h either ultra-lung-protective ventilation combining very low tidal volume (1–2 mL/kg of predicted body weight), low respiratory rate (5–10 cycles per minute), positive expiratory transpulmonary pressure, and 16 h of prone position or lung-protective .

Celine Guervilly (Postdoc 2012-2013), now Research Fellow in Applied Mathematics at the University of Newcastle (UK) Ben Byington (PhD 2014 on "Numerical investigations of novel dynamo processes" with Nic Brummell), now Data Scientist By analogy with rotating convection, the nonlinear upscale transfer of kinetic energy via the Reynolds stresses might require Reynolds numbers of the order of 100 (Guervilly et al., 2014). This might be achievable in fingering convection at lower Prandtl numbers, as Re ℓ is inversely proportional to Pr (Equation 27 or Equation 29 ).
