Hellow everyone! Im trying to simulate the Bartolomej case using the reactingTwoPhaseEulerFoam. Im confused about why my ONB is differernt with the paper? (my case is on the left side and the paper is on the right)
According to the literature, the inlet is 900kg/m2s, the heat flux is 570000w/m2, and the pressure is 45ba

The saturation i used is constant at 45bar and 530.59k.which is same with the licture.I attach the phaseproperties files.
If I am not clear, please let me know so that I can add, thank you!

You may want to refine the grids. The grids in your case and literature may be different.
