droplet evaporation
 

I am currently spraying oil in a combuster. I am using the trap condition for when the droplets touch the wall. How can I calculate the percent of MASS evaporation and MASS trapped? Taking a summary under particel tracking I find that for the particles trapped, Fluent doesnt take the mass evaporated into account. However when tracking a particle I clearly see it is losing mass as it travels. Is there a quick way to find the % mass evaportated for about 20 000 droplets?
