Hi all,

I have simulated water injected to the air.I used DPM with species and pressure-swirl atomizer to accelerate water through nozzles.

The inner diameter of nozzle and pressure were 0.16 mm and 6Mpa respectively.The result of this seems to be good.

However, when I increased inner diameter of nozzle to be 16 mm or more than that,droplets can still evaporate as same as 0.16 mm(100% evaporate).I thought this is wrong.According to the theory of evaporation,the large droplet diameter should almost not evaporate.I try to solve this but I can't reach a good result.

Could anyone suggest me how to solve this problem?

Thank
