Freezing as a Storage Process for Aqueous Polymer Solutions
© Appl. Rheol. 15 (2005) 90-97 Abstract: There is often a need to perform rheological tests on dilute polymeric liquids at a time long after their initial preparation, for example if a more sensitive or novel method of measuring a material property (such as uniaxial/biaxial extensional viscosity or second normal-stress differences) becomes available. An inexpensive method of storing such fluids...
متن کاملA fiber optic sensor for measuring glucose in aqueous solutions
In this paper, the set-up of a multi-mode fiber optic sensor for measuring glucose in aqueous solutions is investigated and evaluated. The basis of this sensor is based on the Fresnel Reflection. In this setup, a helium-neon laser is used as a light source, a fiber optic probe, photocell as detector and a digital multimeter. The statistical analysis of the recorded data shows a highly linear be...
متن کاملTwo-dimensional turbulence of dilute polymer solutions.
We investigate theoretically and numerically the effect of polymer additives on two-dimensional turbulence by means of a viscoelastic model. We provide compelling evidence that, at vanishingly small concentrations, such that the polymers are passively transported, the probability distribution of polymer elongation has a power law tail: Its slope is related to the statistics of finite-time Lyapu...
متن کاملExtensional Relaxation Times of Dilute, Aqueous Polymer Solutions
We show that visualization and analysis of capillary-driven thinning and pinch-off dynamics of the columnar neck in an asymmetric liquid bridge created by dripping-onto-substrate can be used for characterizing the extensional rheology of complex fluids. Using a particular example of dilute, aqueous PEO solutions, we show the measurement of both the extensional relaxation time and extensional vi...
متن کاملTwo-chamber lattice model for thermodiffusion in polymer solutions
When a temperature gradient is applied to a polymer solution, the polymer typically migrates to the colder regions of the fluid as a result of thermal diffusion ~Soret effect!. However, in recent thermodiffusion experiments on poly~ethylene-oxide! ~PEO! in a mixed ethanol/water solvent it is observed that for some solvent compositions the polymer migrates to the cold side, while for other compo...
