How to create an internal surface in a pipe for droplet injection(surface injection) in DPM?
Greetings! I am trying to simulate annular flow in a pipe. I split the tube in 2 zone(stabilization zone and annular zone) .Now I need to inject droplet (surface injection in Discrete phase model) from internal surface of this two zones. The internal surface between this two zones should be used as injection surface.
I hide the stabilization zone and mark the inlet of annular zone as internal surface but when I am checking mesh in fluent ,fluent is throwing this error' velocity-inlet zone 2 has two adjacent cell zones'
Please see the attached image for more clarification.
