Great work Karthi and Francesco!

Lilian had an interesting approach, he checked for the exact geometry and explored several turbulence models. Whereas Vutlapalli had much more rigorous approach, exploring several options with solvers and including a combustion solver. It is a tough call between these two.
I vote Lilian, as I believe the geometry plays an important role in this particular simulation. Numerically I would lean towards Vutlapalli, but this one goes to Lilian.

Good job to all participants!
I would have liked to see more hindsight on this transitional flow at the inlet.
k-epsilon shows the best results for all participants when using RANS but I believe it suffers a case of ''errors are compensating each other and it looks good at the end''. k-epsilon has been shown not to like e.g. secondary flows, big velocity gradients (for example near a stagnation point...).
Why not present your case and opinions
József? :D

This is purely for the community. I have enough spotlight in other events ;) Whom do you prefer?

Tough call. I vote for SC Vutlapali.
Lilian also did well.

Hello, reference paper link fails for me. What is the title of the paper?

[@OpenFOAMJozsefNagy]

Thank you! It was a broken link. Now it should work.

I vote for Eddy Lau. By the way, I encourage viewers to visit his youtube channel, he puts very insightful simulations of water related problems!
