Evaporating Droplet Flow

shashwat

dear all,

I am doing simulation of dilute evaporating droplet phase flow. For this i am solving Carrier phase momentum & continuity equation and droplet phase momentum, continuity equation and number density equation. I am facing difficulty in implementing the vanishing droplet in my code. Can you suggest me something related to implementation. Can we use a limiter on volume fraction or number density below which there will not be any further evaporation & the diameter of the droplet will remain constant. Currently i am considering steady state evaporation and using a constant value of evaporation. Thanks in advance.

Regards!
