Particle Size
(OP)
Ok, this is a stab in the dark. Does anybody know the typical droplet size of generic spray bottles or those pump sprays (like found in hair product stuff or perfume)? I'm trying to find something out there that could simulate in the 1-20 micron range, but something tells me a spray bottle's droplets are much bigger than this. If anybody has any info or might know something I could put together around the house or put together really cheap...pass it along. Thanks!

To get to an actual aerosol you have to add considerable energy to overcome surface tension. The only houshold product I can think of that does this is a nebulizer that people use for asthma relief.

I once used a nozzle off my wife's perfume bottle to feed a V1 rocket motor combustion chamber inlet. It worked rather well for a while, but started melting with increasing thermal outputs. Then the Reed Valves gave out. I was interested in the "fuel mist" because of air/fuel ratios and tried to make an electrostatic generator to suspend the particles against gravity. I think Milligan Oil Drop Experiment comes to mind in my university days. Nothing ever developed from that.
But nebulizers for asthma relief would be an interesting application for the design.
