Drop Impact Viscometry (DIV): Drop Impact on a Spherical Target

A novel method to measure viscosity has been developed by ESR05 using drop impact on a spherical target shown in the sketch below. It relies on high-speed imaging and analysis of the fluid mechanics using a theory developed specifically for this problem.  A water drop impact example is shown in the video below. The method is currently being upgraded to study nanosuspensions and nanoemulsions.
