The quantity of the droplet relative to the surrounding supplied air is very small (&lt;&lt; 10%) and since the temperature of air is much higher than that of the ammonia droplets (30 C vs -33 C), the droplets are expected to gradually vaporize (thus resultant vapor will be in the air phase).&nbsp;&lt;\/span&gt;&lt;\/p&gt;&lt;p&gt;&lt;span style=&#8221;font-size: 12pt;&#8221;&gt;Intuitively, DPM (coupled with phase change through multiphase) is the way to go. However, the default Material Droplet Particle database doesn&#8217;t have the droplet properties for Liquid Ammonia (the only choice automatically assigned is Argon-Liquid). I don&#8217;t see any way to create the new Liquid Ammonia droplet, and when I tried to make one I was flagged for already having Liquid Ammonia properties (in Material &gt; Fluids). And even if I succeed, I don&#8217;t know how to couple it with the phase change (vaporization) model.&nbsp;&lt;\/span&gt;&lt;\/p&gt;&lt;p&gt;&lt;span style=&#8221;font-size: 12pt;&#8221;&gt;I wonder if anyone has encountered the same problem or solution for the problem.
