There will be very less droplet deposition near the injection surface but deposition should increase towards the outlet(away from injection surface). Droplets have random velocity away from injection surface(please see the attached image). So, the probability to touch the liquid film/film wall should increase, means more deposition.
If above assumption is wrong , then how can I inject droplets in the tube to simulate core( vapor is continuous phase and liquid droplets are discrete phase) of annular flow.? If the droplets touch the liquid film formed on the wall by EWF , it should be trapped there.
Here I am thinking to simulate 'liquid film' by EWF and 'core '( continuous vapor phase and discrete liquid droplet phase) by DPM to simulate annular flow in a pipe.
Moreover, It's a vertical tube and flow is going upward.
