Resolving the stratification discrepancy of turbulent natural convection in differentially heated air-filled cavities – Part I: Reference solutions using Chebyshev spectral methods

► Spectral 3D DNS results are presented for turbulent differentially heated cavity. ► Adiabatic or measured temperature distributions applied at the top and bottom walls. ► Experimental thermal stratification is incorrectly predicted with the set BC. ► Part 2 LES show that experimental temperature d...
