WebHowever, these methods may not be suitable for materials with low electrical conductivity. The pendant drop, sessile drop, and maximum bubble pressure methods have been used to determine the surface tension of molten metal systems, but become more difficult to use at high temperatures due to difficulties in maintaining homogeneous temperature WebThe Z-number is defined as Z ¼ ðr s dÞ0:5 =Z ð2Þ where r is the fluid density, s its surface tension, d is a characteristic dimension (nozzle diameter) and Z is the dynamic viscosity. The condition of Z42 has been reported as the lower limit for a fluid to be printable, while satellite droplet formation becomes likely if Z410 (Fakhfouri et al., 2009).
Web1.1. Sessile drops of volatile liquids. The dynamics of the liquid–vapour phase change, i.e. evaporation and condensation, plays a very important role in many systems involving films or drops of simple or complex liquids on solid substrates (Brutin Reference Brutin 2015).Examples of practical importance include printing, coating and deposition … WebThe surface tension of molten SUS304 and 316 stainless steels was measured over a wide temperature range includ-ing an undercooling condition under flow conditions of Ar– He and Ar-He-5 vol.%H2 mixed gases by an oscillating droplet method using EML.
