Abstract
When droplets are vibrated or disturbed, they can exhibit a complex sloshing motion, an understudied behavior in drop physics. Droplet sloshing involves a complex combination of transverse and longitudinal motion that changes the droplet's effective weight on the surface the droplet is on. Our current understanding stems from preliminary work focusing on a cantilever beam of fixed thickness and variable viscosity of the liquid being sloshed. This investigation will focus on how variable cantilever thickness and constant viscosity for a liquid being sloshed affects the beam's deflection under consistent vibration. It will also investigate how the natural frequency of a stationary droplet is affected by variable viscosity and volume when disturbed. The investigation revealed an inverse relationship between the thickness of the Kapton cantilever and the beam displacement. It is observed that an inverse relationship exists between drop volume and natural frequency. Moreover, comparing drops with the same volume but different viscosities showed that increasing the viscosity tends to decrease the natural frequency.
