SURFACE TENSION AND VISCOSITY MEASUREMENT WITH SURFACE LASER LIGHT SCATTERING METHOD

ABSTRACT
Measurement of thermal properties is an important topic in the thermophysics. With the developing of laser technology, laser detection technologies can be used for thermal properties measurement. Based on the laser light scattering theory and light heterodyne detection principle, an experimental system by the surface laser light scattering is developed to measure the liquid surface tension and viscosity simultaneously. The maximal experimental errors of the measured surface tension and viscosity are less than 0.5% and 4.73%, respectively.
