Weak Turbulence in Small Prandtl Number Convection in Porous Media

, 2010
The dynamics of weak turbulence in small Prandtl number convection in porous media is substantially distinct than the corresponding dynamics for moderate and large Prandtl numbers.

Double-Diffusive Convection at Low Prandtl Number

, 2018
This work reviews present knowledge of double-diffusive convection at low Prandtl number obtained using direct numerical simulations, in both the fingering regime and the oscillatory regime. Particular emphasis is given to modeling the induced turbulent

On the Onsetof Thermal Instability in a Low Prandtl Number Nanofluid Layer in a Porous Medium

Journal of Applied Fluid Mechanics, 2015
Thermal instability in a low Prandtl number nanofluid in a porous medium is investigated by using Galerkin weighted residuals method for free-free boundaries. For porous medium, Brinkman-Darcy modelis applied.

Numerical Simulation of Turbulent Channel Flow at Low Prandtl Number [PDF]

, 2016
Liquid metals are primary coolants in Generation IV nuclear reactors. For low Prandtl\ud fluids, such as liquid metals, classical Reynolds analogy of using turbulent Prandtl number\ud close to unity doesnt predict heat transfer characteristics ...

Laminar Natural Convection of Newtonian and Non – Newtonian Fluids Inside Triangular Enclosure

Al-Khawarizmi Engineering Journal, 2007
In the present work, steady two – dimensional laminar natural convection heat transfer of Newtonian and non-Newtonian fluids inside isosceles triangular enclosure has been analyzed numerically for a wide range of the modified Rayleigh numbers of (103 ...

Asymptotic Behaviour of Galactic Small-scale Dynamos at Modest Magnetic Prandtl Number

The Astrophysical Journal Letters
Magnetic fields are critical at many scales to galactic dynamics and structure, including multiphase pressure balance, dust processing, and star formation. Dynamo action determines their dynamical structure and strength.
