WebThe balance between extensional and capillary stresses is carried out assuming inertial and viscous terms are negligible. Here, capillary stress depends on the ratio of surface tension, σ to the transient neck radius. WebThe CaBER®, or Capillary Breakup Extensional Rheometer, is a low cost, easy to use instrument for quantifying the flow response of a polymer liquid and melt to an …
High-temperature extensional rheology of linear, branched
WebMar 23, 2024 · Capillary rheometry has been typically used for determining the viscosity curves of polymer melts, providing reliable information at high shear rates, beyond the limits of rotational rheometers, and in similar conditions to the industrial process. WebOct 1, 2010 · We use capillary thinning of a filament that is formed by a polymer solution in the Capillary Breakup Extensional Rheometer (CaBER) as an elongational flow. We compare the relaxation time measured in the CaBER with relaxation times based on the first normal stress difference and the zero shear polymer viscosity that we measure in our … tibia great swordsman

Webrheometer that can provide rapid results in the field. First, we investigated the sensi-tivity of capillary breakup measurements, the method chosen for measuring elasticity, to initial stretch parameters in using the commercial, Capillary Breakup Extensional Rheometer (CaBER), using analog polymer solutions. Finally, our study highlighted WebFollowing the original analysis by Entov and coworkers [9, 10, 11], capillary thinning rheometry has be-come a standard technique for rapidly measuring the extensional properties of a wide range of viscoelastic uids, including polymer solutions.
