Nuclear heat transfer applications with low-Prandtl number fluids are often in the transition
range between conduction and convection dominated regimes. Most flows in reactors …

Experimental limitations for certain nuclear reactor safety applications have pushed forward
the demand for high fidelity DNS reference solutions for complex geometric configurations …

The critical review discusses the most accurate methods for description of turbulent flows:
the computationally very expensive direct numerical simulation (DNS) and slightly less …

Turbulent mixing of fluids at different temperatures can lead to temperature fluctuations at
the pipe material. These fluctuations, or thermal striping, inducing cyclical thermal stresses …

High cycle thermal fatigue failure in a nuclear power plant T-junction piping system may be
caused by near-wall temperature fluctuations due to thermal mixing of hot and cold fluid …

This paper presents wall-resolved Large-Eddy Simulations (LES) of thermal mixing
mechanisms both in horizontal and vertical T-junctions. The mass flow rate ratio (m ̇ m/m ̇ …

In this paper we report on a direct numerical simulation (DNS) of turbulent heat transfer in a
T-junction. In particular, we study the interaction between two liquid streams, a hot horizontal …

High cycle thermal fatigue (HCTF) damage in the vicinity of T-junction piping, where mixing
of coolant streams at significant temperature differences occur, is considered to be an …

In this paper we present a detailed study of turbulent mixing between a cold crossflow and a
hot incoming jet in a T-junction. Our study is based on wall-resolved and experimentally …
