About

Organiser: Jožef Stefan Institute (JSI) (Slovenia), in collaboration with The University of Manchester and Imperial College London (United Kingdom).

A workshop on turbulence modelling of natural convection is proposed. It will consist of a single track of keynote lectures, short research presentations and panel discussions. Expected contributions include RANS, hybrid RANS-LES and LES.

Turbulent natural convection in wall-bounded configurations have been the focus of a number of studies in the past. However, it is only recently that we have obtained DNS-quality validation data for advanced RANS models for the square cavity case with a 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 a vertical plane channel by Kiš and Herwig (February 2014, 10.1007/s00231-014-1305-5). Registered participants are welcome to submit their simulation results, alongside with a complete description of the turbulence model used.

The DNS data for the square cavity case are available in this archive (27 MB). The selected DNS data for the vertical plane channel are available in this archive (0.3 MB).

How to reach Ljubljana:

• by Ljubljana airport
  Ljubljana airport is located about 20 km North of Ljubljana - in the direction Kranj.
• by train
  Ljubljana railways connecting Austria (Graz, Klagenfurt), Italy (Trieste). Main train station is in the city centre. The train-airport connections can also be an option.
• by bus: www.ap-ljubljana.si/
  The web site of the Ljubljana Bus station (Avtobusna postaja Ljubljana) offers timetables for all local bus connections, including the plan of the bus routes. The ticket office is open daily from about 5.00 or 5.30 till 22.30. For most of the routes you can buy the tickets directly from the driver. Please have small denomination Euro notes and coins ready.
