A robust method for calculating interface curvature and normal vectors using an extracted local level set [PDF]
, 2014 The level-set method is a popular interface tracking method in two-phase flow simulations. An often-cited reason for using it is that the method naturally handles topological changes in the interface, e.g.

Lamellar thickness and stretching temperature dependency of cavitation in semicrystalline polymers. [PDF]
PLoS ONE, 2014 Polybutene-1 (PB-1), a typical semicrystalline polymer, in its stable form I shows a peculiar temperature dependent strain-whitening behavior when being stretched at temperatures in between room temperature and melting temperature of the crystallites ...

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 ...

Design and placement of synthetic sex pheromone traps for cacao mirids in Ghana [PDF]
, 2018 Cacao mirids (Sahlbergella singularis, Distantiella theobroma and Bryocoropsis laticollis) were captured in pheromone traps releasing a 2:1 blend of the sex pheromone components of the two first named species in a series of five experiments on cacao ...

On the Influence of Concentration on the Rheology of Polymer Solutions: Can Scaling Laws Be Found?
Applied Rheology, 2003 The present work is concerned with the study of the rheology of polymer solutions spanning different concentration regimes and originates from a former round-robin research programme on this subject, the S1 project, involving a number of research groups ...
