Hail to all magnificent physicists from a humble chemist! :)
I'm working on an experimental setup for investigation of homogeneous nucleation and crystal growth in container-free environment. Well, actually, just trying to think about all potential pitfalls and problems before designing any actual apparatus.
I've thought and get to know about many terrestrial options for "levitating" a droplet of liquid, and settled for aerodynamic levitation, as any other option requires high voltage, enormous magnetic fields or lasers to work with non-conducting, room temperature samples. My budget and I prefer cheap and mendable options.
So, idea is to setup variable speed/variable temperature stream of gas (i.e. nitrogen) which is saturated with liquid vapour to prevent evaporation of droplet. Gas would be flowing in upward direction and in laminar fashion. Furthermore, liquid is a pure substance with known and well defined physical properties (density, surface tension, possibly anything that could be used to model this problem).
My questions are:
Is there any known oh-yes-this-works-for-this model or simulation tool with which I could predict what would happen with liquid droplet in that gas stream? (by so, ignoring evaporation and any boundary conditions except for one between gas and liquid droplet) If not, could you suggest where to start?
Is there any way to predict maximum spherical droplet size which would remain stabile (which would not disintegrate into smaller droplets). If not, are there any special shapes which would be stabile in this environment?
