Hi Everyone ,

I am simulating flow boiling on VoF multiphase model for water through a rectangular channel of 10mm × 1mm with a inlet velocity of 0.1m/s with a heat flux of 25 KW/m2 applied on walls. The temperature at inlet is 372.15 K.
It is giving me slug flow as shown below in link. but I am unable to get bubbly flow …bubble are not getting detached from the walls . I am working on Ansys Fluent 2022 R2.

For initial bubbles formation I have adapted the regions but when I go to results it gives error and does not show any results.
