Forced convection for capillary evaporation

ralmeida

I was wondering what other evaporation mechanisms take place apart from evaporation due to natural convection from a micro capillary. I was trying to describe the evaporation process by diffusion due to convection in a micro nozzle. What other mechanisms I'll have to consider? Any ideas would really help. I can attach the formulas I've been trying to explain my application with.
