DNS and LES database of turbulent heat transfer in a channel at very low Prandtl number

The data available for download on this web page were obtained in the framework of the THINS (Thermo-Hydraulics for Innovative Nuclear Systems) FP-7 project. They are described in in the Delivrable D3.1.01 of the THINS project and in the following papers: * Direct and large eddy simulation of turbulent heat transfer at very low Prandtl number: Application to lead–bismuth flows, L. Bricteux, M. Duponcheel, G. Winckelmans, I. Tiselj, Y. Bartosiewicz (http://dx.doi.org/10.1016/j.nucengdes.2011.07.010) * Assessment of RANS and improved near-wall modeling for forced convection at low Prandtl numbers based on LES up to Re_tau = 2000, M.Duponcheel, L.Bricteux, M.Manconi, G.Winckelmans, Y.Bartosiewicz (https://doi.org/10.1016/j.ijheatmasstransfer.2014.03.080) Please cite the paper when using the data. The following cases are available: Re_tau Pr Lx/h x Ly/h x Lz/h nx x ny x nz DNS 180 0.01 2*pi x 2 x pi 128 x 128 x 128 DNS 590 0.01 – 0.025 5.75 x 2 x 2.9 384 x 384 x 384 LES 590 0.01 – 0.025 2*pi x 2 x pi 96 x 64 x 96 LES 640 0.01 – 0.025 2*pi x 2 x pi 96 x 64 x 96 LES 2000 0.01 – 0.025 2*pi x 2 x pi 384 x 256 x 384 Note : the DNS at Re_tau = 590 is not fully converged. We recommend to use of the spectral database of I. Tiselj from JSI. Those data were previously hosted at https://comete.meca.ucl.ac.be/vortex/channel/index.htm
