Abstract
For this workshop, a backward facing step flow problem with a heated wall below the supply opening was studied using computational fluid dynamics (CFD) by a total of 32 teams from all over the world. We presented a summary of these results in the workshop, followed by a discussion by the participants. The results show a very large spread in predicted values of the penetration length (xre/(H-h)), the location of maximum velocity in the lower part of the recirculation cell (xrm/(H-h)) and the maximum velocity at this location (urm/u0). There appears to be a very strong influence of the turbulence model on the results, with a clear difference in predictions by the k-ε models and the k-ω models. Participants discussed about the reasons behind the observed large differences in the predicted results.
