Description

This paper presents recent developments of DNS (Direct Numerical Simulation) and LES (Large Eddy Simulation) for liquid metals with a focus on local heat transfer behavior.Three Reynolds number are considered, namely Reτ = 180, Reτ = 590, and Reτ = 640. For the two higher Reynolds hybrid LES/DNS are performed and gives satisfactory results compared to reference DNS. The analysis of wall heat transfer behavior allows to propose new best practice guidelines for RANS computations. Usual correlations for the overall wall heat transfer coefficient are also compared to the present results. (author)
