Computational Predictions for Boger Fluids and Circular Contraction Flow under Various Aspect Ratios
Fluids, 2020 This work puts forward a modeling study contrasted against experimental, with focus on abrupt circular contraction flow of two highly-elastic constant shear-viscosity Boger fluids, i.e., a polyacrylamide dissolved in corn-syrup PAA/CS (Fluid-1) and a ...

Crystallization kinetics and polymorphic transformations in polybutene-1
Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1965 When subcooled from the melt to any temperature between about 90 to 110 °C, polybutene-1 transforms at a readily measurable rate to a crystalline phase denoted "form 2," which is typically spherulitic. The kinetics of this process have been measured by optical and dilatometric techniques. The results are consistent with the concepts that the initiation

Business Strategy and the Environment, EarlyView.ABSTRACT This study examines how plastics manufacturing firms can be classified according to their level of implementation of circular economy (CE) and industrial symbiosis (IS) practices and how such adoption influences sustainability performance. Using data from plastics manufacturing firms, we integrate cluster analysis with partial least squares ...
