Capillary breakup rheometry is an experimental technique used to assess the extensional rheological response of low viscous fluids. Unlike most shear and extensional rheometers, this technique does not involve active stretch or measurement of stress or strain but exploits only surface tension … See more Capillary breakup rheometry and its recent development are based on the original experimental and theoretical work of Schümmer and Tebel and Entov and co-workers. Nonetheless, this technique found his origins at … See more Capillary thinning and breakup of complex fluids can be studied using different configurations. Historically, mainly three types of free-surface conformations have been employed in … See more The behaviour of the fluid determines the relative importance of the viscous and elastic terms in resisting the capillary action. Combining the force balance with different … See more There are many processes and applications that involves free-surface flows and uniaxial extension of liquid filaments or jets. Using capillary breakup rheometry to quantify the dynamics of the extensional response provides an effective tool to control … See more The temporal evolution of the thinnest region is determined by a force balance in the fluid filament. A simplified approximate force balance can … See more CaBER The CaBER (Capillary Breakup Extensional Rheometer) is the only commercially available instrument based on capillary … See more • Fluid thread breakup • Plateau–Rayleigh instability • Rheometer • Visco-elastic jets See more WebHaake Capillary Breakup Extensional Rheometer (CABER) Allows the determination of the extension characteristics of non-newtonian fluids. Modified by our group for additional force detection. Now its is possibible to measure elongation and force simultaneously. ...
