Turbulent heat transfer is a complex phenomenon, which is ubiquitous in engineering
applications and has challenged turbulence modellers for several decades. In an attempt to …

Thermal-hydraulics is recognized as a key safety challenge in the development of liquid
metal cooled reactors. At nominal operating conditions, the Prandtl number of liquid metals …

The present work evaluates the performance of different RANS turbulence models in a
natural convection boundary layer at three different Prandtl numbers: 0.71, 0.2 and 0.025 …

The paper presents the direct numerical simulation (DNS) of a confined backward facing
(BFS) step geometry with a flow of two fluids with Prandtl numbers 0.005 and 0.1. The …

In the numerical simulation of turbulent heat transfer, a reliable representation of the
turbulent flow field is a prerequisite in order to obtain an accurate prediction of the thermal …

Liquid metal cooled reactors are envisaged to play an important role in the future of nuclear
energy production because of their possibility to use natural resources efficiently and to …

In the present study, we have applied a combined wall-resolving dynamic Large-Eddy
Simulation (LES)(for the velocity field) and Direct Numerical Simulation (DNS)(for the …

DNS simulations of planar impinging jets are performed to provide reference data to validate
RANS models for low-Prandtl turbulent heat transfer. In that configuration, a hot plane jet is …

In the present work, we have applied a combined dynamic large-eddy simulation (LES) and
direct numerical simulation (DNS) approach for a three-dimensional planar jet in a turbulent …

This paper attempts to give a brief overview of the work conducted through some recent EU
funded projects under the Euratom research for innovative nuclear systems (THINS …
