The settings are as follows:
The phenomenon is steam jet condensation into a water tank。
Particle model was applied in the model, steam as dispersed phase and water as continuous fluid. As to fluid models, both phases was set by thermal energy.
The boundary condition: the steam inlet condition was mass flow rate condition. The outlet boundary is set as opening condition,the entrainment pressure is 0 Pa.
Solver control-advection scheme-high resoluton. Physical timescale is 1e-06s.
I can get the following results(void fraction at a axial cross section):


The void fraction profile by other researchers is:


Anyone can tell me why I can't get the results as other's? Thank you so much if you can read my thread.

And are you sure you have run your model for enough physical time? And that it is converged?

Also - you show one image going up, one down and the work by other researchers goes across. Does the direction (relative to gravity, I presume) make any difference?

Thanks for your kind reply. I will check it as your advice.
