A laboratory-scale experiment and a numerical simulation of unusual spiral plumes in a High-Prandtl-number fluid, links supplementary material

, 2014
We experimentally and numerically investigated the generation of plumes from a local heat source (LHS) and studied the interaction of these plumes with cellular convective motion (CCM) in a rectangular cavity filled with silicon oil at a Prandtl number ...

Enhancing Thermal-Hydraulic Modelling in Dual Fluid Reactor Demonstrator: The Impact of Variable Turbulent Prandtl Number

Energies
In response to the growing demand for advanced nuclear reactor technologies, this study addresses significant gaps in thermal-hydraulic modelling for dual fluid reactors (DFRs) by integrating Kays correlation to implement a variable turbulent Prandtl ...

Patterns and bifurcations in low–Prandtl-number Rayleigh-Bénard convection

, 2010
We present a detailed bifurcation structure and associated flow patterns for low–Prandtl-number (P=0.0002, 0.002, 0.005, 0.02) Rayleigh-Bénard convection near its onset.

Stationary statistical properties of Rayleigh-Bénard convection at large Prandtl number

, 2006
This is the third in a sequel in our study of Rayleigh-Bénard convection at large Prandtl number. More specifically we investigate if stationary statistical properties of the Boussinesq system for Rayleigh-Bénard convection at large Prandtl number are ...

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.

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

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 ...
