Injection of water in vapor
 

Hi to all! My problem: i have to simulate an injection (continuos flow) of water, 2,5 Kg/s, in a flow of vapor in supercritical condition (110 bar, 814K); the flow of vapor is in steady condition, 50 Kg/s. I want to know the time of complete evaporation of water injected, take for granted that i know the exact diameter of the droplets of water. My idea is to do a steady simulation, with only the injected phase in unsteady condition...and to use a model of injection already implemented in Fluent. Suggestions??? I'm a little confused.
