Effect of Elongational Viscosity on the Flow in a Spiral Die
نویسندگان
چکیده
Three-dimensional flow of a low-density polyethylene in a spiral die for blown-film extrusion is simulated. Effect of elongational viscosity on the flow in the spiral die is analyzed. Elongational viscosity is found to have significant effect on the velocity distribution at the die exit and on the pressure and temperature distributions in the die.

Simulation of Polymeric Flow in a Twin-screw Extruder: an Analysis of Elongational Viscosity Effects
Flow of a polymer in an intermeshing co-rotating twin-screw extruder is simulated. Effect of elongational viscosity on the flow is analyzed using independent powerlaw models for the shear and elongational viscosities. Axial component of the velocity is found to be maximum in the intermeshing region of the extruder. Axial component of velocity, which determines the throughput of the extruder, de...
متن کاملIs there a Relationship between the Elongational Viscosity and the First Normal Stress Difference in Polymer Solutions?
We investigate a variety of different polymer solutions in shear and elongational flow. The shear flow is created in the cone-plate-geometry of a commercial rheometer. 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 and the elongational viscosity measured i...

The rheology of a dilute suspension of chains of magnetic particles is being studied in order to elucidate the effect of the dipolar magnetic interactions on the chains’ contribution to the pressure tensor and to the viscosities of the suspension. Depending upon the nature of the elongational flow, the rigid chain-limiting behavior of the pressure tensor as well as that of the elongational, she...
متن کاملPrimitive chain network simulations for elongational viscosity of bidisperse polystyrene melts
Background Due to the industrial significance, elongational viscosity of polymeric liquids has been widely investigated. In particular, strain hardening, which is the deviation of the elongational viscosity from the linear viscoelastic envelope, has been of industrial and scientific interest because polymeric liquids exhibiting strain hardening are suitable for processing technologies with elon...
متن کاملThe effect of micro/nano-particles on pressure drop in Oil pipeline: Simulation
A high pressure drop happens when heavy oil with high viscosity moves through the oil pipeline. A variety of methods to avoid this pressure drop is available. One of which is injection of chemicals to reduce the viscosity and ultimately reduce pressure drop. Using the pipesim software, the effect of dispersion of nano and micro-particles into the oil has been simulated to study the amount of th...
