  • Method for determining elongational viscosity and dynamic surface tension in liquid solutions
    Patent number: 5559284
    Abstract: Disclosed is a method for measuring intermolecular force related physical properties of an objective liquid such as elongational viscosity and dynamic surface tension, comprising the steps of atomizing neat liquids to a particle size in a gaseous fluid stream, measuring the particle size of the atomized neat liquid, determining an empirical expression based on known physical properties of the neat liquid and the atomization conditions, and using the empirical expression and identical atomization conditions to rapidly determine the unknown intermolecular force related physical properties of the objective liquid, the objective liquid being another neat liquid or a liquid in which a solute is dissolved.
