DNS-Database

DNS DATABASE OF TURBULENT NATURAL CONVECTION IN HORIZONTAL FLUID LAYERS

This site provides a collection of data files containing turbulent statistical quantities obtained through various direct numerical simulations (DNS) of the Rayleigh-Bénard convection and the convection in an internally heated fluid layer, performed with the computer code TURBIT. You can freely download the data files for your own research purposes, but may not use them for any commercial purposes (Please note the restrictions).
