Limitation in Discrete Particle Model

Woo Meng Wai

Dear All,

I am having problem tracking the evaporation of droplets in my DPM model. The initial droplet condition used is 80 %volatile. But the mass of the droplet suddenly drops to 0 %volatile. This consistently occurs toward the latter stages of evaporation, at around 4 % volatile (~ 5.797-5.825 e-13 kg in droplet mass).

1. Is this a limitation in the mass tracking in FLUENT DPM? 2. If it is, any solution for this?

Thank you all. Hope some one can help me on this.

Regards, Woo
