Hydromagnetic dynamos at the low Ekman and magnetic Prandtl numbers

open access: yesContributions to Geophysics and Geodesy, 2016
Hydromagnetic dynamos are numerically investigated at low Prandtl, Ekman and magnetic Prandtl numbers using the PARODY dynamo code. In all the investigated cases, the generated magnetic fields are dominantly-dipolar.

Sublayer of Prandtl Boundary Layers [PDF]

open access: yesArchive for Rational Mechanics and Analysis, 2018
The aim of this paper is to investigate the stability of Prandtl boundary layers in the vanishing viscosity limit: $ν\to 0$. In \cite{Grenier}, one of the authors proved that there exists no asymptotic expansion involving one Prandtl's boundary layer with thickness of order $\sqrtν$, which describes the inviscid limit of Navier-Stokes equations.

Development of New Turbulent Prandtl Number Models for Low- and Medium-Prandtl-Number Fluids via Multi-Gene Gene Expression Programming

open access: yesApplied Sciences
The study of turbulent Prandtl number is important for turbulent flows with heat transfer. Despite its importance, no universal model exists that is able to capture its behavior for a range of molecular Prandtl numbers.
