Abstract Scope |
Imaging of sessile droplets of FLiBe and FLiNaK has generated a few different types of data sets of thermo-physical properties of the salts. The experimental setup consists of a furnace to melt salt samples on the plates observed with a digital camera. The wetting behavior of FLiBe and FLiNaK on graphite plates has been investigated by quantifying the contact angle. The surface tension of the salts has been estimated from drop shape analysis. The transient volumetric change through freezing was quantified from drop volume analysis. The solidification and melting phenomena were visualized, observing homogeneous in FLiNaK and heterogeneous nucleation in FLiBe; from DSC, FLiBe was observed to exhibit deep supercooling. This talk will provide a summary of thermo-physical properties that can be derived from high-resolution images of sessile molten salt droplets and from high-resolution videos of thermal transients experienced by sessile droplets. |
