Step Date Type Process Changes #1 mechanical Liquid water droplets are produced using Flow Blurring® Nebulizer-FBM 2mm (Ingeniatrics). Flow Blurring nebulization employs highly turbulent mixing between the nebulizer gas flow (here 1.0±0.1 bar) and the liquid flow (here 100 mL/min). This technique creates an aerosol with extremely fine micro scale droplets. Spherical liquid water droplets are formed. #2 thermal The droplets of deionized/ultra-pure water, initially liquid, undergo solidification as they contact the liquid nitrogen. Spherical water ice particles are formed.
