Modelling of wall bounded turbulent natural convection, a re-assessment using state-of-the-art massively parallel DNS

Date: 15th & 16th October 2019

                                      Dr Sofiane Benhamadouche, EDF

Description:

Turbulent natural convection in wall-bounded configurations have been the focus of a number of studies in the past and remains a modelling challenge as application of turbulence models initially developed for forced convection flows to buoyancy driven flows is inappropriate. It is only recently that we have obtained DNS-grade validation data for advanced RANS models for the square cavity case – with mean horizontal temperature gradient – at a sufficiently high Rayleigh number.

The main objective of the workshop is to re-assess turbulence models for natural convection with the square cavity DNS by Frederic Sebilleau and co-workers (January 2018, 10.1016/j.ijheatmasstransfer.2018.02.042) and the simpler case of turbulent natural convection in vertical plane channel by Kiš and Herwig (February 2014, 10.1007/s00231-014-1305-5).

The 16th ERCOFTAC SIG15 Workshop on turbulence modelling will consist of a single track of keynote lectures, short research presentations and panel discussions.
