Elastic instabilities of polymer solutions in cross-channel flow.
When polymer molecules pass near the hyperbolic point of a microchannel cross flow, they are strongly stretched. As the strain rate is varied at low Reynolds number (< 10(-2)), tracer and particle-tracking experiments show that molecular stretching produces two flow instabilities: one in which the velocity field becomes strongly asymmetric, and a second in which it fluctuates nonperiodically in...
متن کاملThermodynamics of Polymer Solutions
Most of the synthetic compounds are prepared and processed in the liquid state, i.e. in solution or in the molten state. Detailed knowledge on this state is therefore indispensable. In particular it is essential to know the limits of complete miscibility with a low molecular weight solvent as a function of temperature, pressure and composition. Furthermore it is often mandatory to be acquainted...
متن کاملTurbulence of polymer solutions.
We investigate high-Reynolds-number turbulence in dilute polymer solutions. We show the existence of a critical value of the Reynolds number, which separates two different regimes. In the first regime, below the transition, the influence of the polymer molecules on the flow is negligible, so they can be regarded as passively embedded in the flow. This case admits a detailed investigation of the...
متن کاملCritical polymer-polymer phase separation in ternary solutions.
We study polymer-polymer phase separation in a common good solvent by means of Monte Carlo simulations of the bond-fluctuation model. Below a critical, chain-length-dependent concentration, no phase separation occurs. For higher concentrations, the critical demixing temperature scales nonlinearly with the total monomer concentration, with a power law relatively close to a renormalization-group ...
متن کاملViscoelastic properties of polymer solutions.
In a concentrated polymer solution, the entanglement of long-chain molecules results in a transient network structure, to which may be attributed certain aspects of the viscoelastic behavior of such a system. A suitable mechanical model for representing this network as a first approximation is a retarded Maxwell element with one spring and two dashpots. Experimental measurements of mechanical p...
