摘要: Abstract Liquid–liquid interfacial tension plays a crucial role in multiphase systems the chemical industry. The available measurement methods for liquid–liquid are poorly suited to low bond number systems, which often found industrial processes. This study developed and verified new method of calculating by using “submerged holm” meniscus. holm meridian was experimentally formed around solid object submerged at interface. A program MATLAB calculate from meridian. calculated be consistent with data multiple oil–water systems. is first time meniscus has been used successfully determining tension. More importantly, applicable small density difference between two phases. As demonstration, silicone oil (1000 cP) – water measured, where less than 30 kg/m 3 (3%). potentially suitable processes involving hazardous or unstable chemicals, elevated pressure temperature.
