- Abstract
- This paper is concerned with comparing different approaches for the numericalprediction of heat transfer in a turbulent channel flow at very low Prandtl number and highReynolds number. Results obtained with a Reynolds Averaged Navier Stokes (RANS) approachat relevant Reynolds numbers for the liquid metal reactor problematic (Reτ = 590, Reτ = 1020),are presented and discussed. Original results obtained with a wall resolved Large EddySimulations (LES) at Reτ = 2000 are provided. The velocity profile agrees very well withthat of a reference Direct Numerical simulation (DNS). The obtained temperature profile canserve as a reference as the energy equation is computed without any Subgrid Scale (SGS) modelat this low Pr.
