| Abstract(in English) | Rayleigh type SAW (surface acoustic wave) radiates a longitudinal wave into a liquid when the SAW propagation surface is in contact with the liquid. If the SAW power is raised above a certain threshold value, the liquid begins to stream. We call these phenomena SAW streaming. In this study, we vibrate the liquid droplet by using this SAW streaming and measure the frequency and the decay constant of the free vibration. The vibration is influenced by such parameters as the droplet volume (radius of droplet), contact angle, density, surface tension and viscosity. This paper describes a new method for the measurement of the liquid physical properties. If the volume and density of the liquid are known, we can determine the viscosity from the decay constant of the free droplet vibration, and the surface tension and the contact angle from the free vibration frequency. |
