In assessing whether nuclear plant components such as T-Junctions are likely to suffer
thermal fatigue problems in service, CFD techniques need to provide accurate predictions
for wall temperature fluctuations. Though it has been established that this is within the
capabilities of wall-resolved LES, its high computational cost has prevented widespread
usage in industry. In the present paper the suitability of LES with blended wall-functions, that
allow the first cell to be placed in any part of the boundary layer, is assessed. Numerical …
