This paper covers work carried out by the CEA to study the mechanisms leading to cracking
of piping as a result of thermal loading in flow mixing zones. The main goal of the work is to …

Abstract Hybrid Reynolds-Averaged Navier-Stokes–Large Eddy Simulation was used to
reveal detailed flow information and timescales in an isothermal reactor cavity cooling …

A rational analysis method for thermal stress induced by fluid temperature fluctuation is
developed, by utilizing frequency response characteristics of structures. High frequency …

Fatigue cracks have been found at mixing tees where fluids of different temperature flow in.
In this study, the thermal stress at a mixing tee was calculated by the finite element method …

This study was aimed at identifying the constraint conditions under local temperature
fluctuation by thermal striping at a mixing tee and by thermal stratification at an elbow pipe …

Fatigue damage of stainless steel was assessed by crack growth analysis. In order to
characterize small crack initiation and growth, fatigue cracking behavior was observed by …

The impulse response method is applied to the analysis of the thermally striped internal
surface of a hollow cylinder containing a circumferential crack on this surface. Stress …

In order to assess the crack growth due to thermal fatigue caused by a local temperature
fluctuation, it is important to consider the stress gradient in the thickness direction. Even if the …

This study considers surface crack behaviour under periodic thermal loads using weight
functions and finite element calculations. A surface and subsurface crack opening mode …

The random temperature fluctuation produced by the incomplete mixing of hot and cold fluid
streams passing over the surface of a component or structure is known as thermal striping …
