Turbulent natural convection in wall-bounded configurations, in particular differentially heated cavities, have been the focus of a number of studies in the past, due to their relevance for different industrial configurations, such as nuclear power plants, underhood of road vehicules, buildings, etc. However, it is only recently that we have obtained sufficiently high Rayleigh number data (experimental and DNS data) for the validation of advanced RANS, hybrid RANS/LES or LES models.

Following the 16th ERCOFTAC SIG-15 workshop held in Ljubljana in 2019, the 17th workshop will focus on the DNS database of the square cavity case by Frederic Sebilleau and co-workers at Ra=10^11. In addition, the very recent experimental database of Weppe and co-workers (MONACO_2025 project) of a cubic cavity with a partially heated inner block at Ra=1.4 x 10^9 (based on the inner-block height), will be considered.
