Realization of Intermolecular Interactions as a Basis for Controlling Pervaporation Properties of Membranes Made of Aromatic Polyamide-Imides by Svetlana V. Kononova, Galina N. Gubanova, Galina K. Lebedeva, Elena V. Kruchinina, Elena N. Vlasova, Elena N. Popova, Natalya V. Zakharova, Milana E. Vylegzhanina, Elena A. Novozhilova, Ksenia V. Danilova

“…High levels of membrane permeability accompanied by high selectivity for mixtures of liquids with significantly different polarities were determined by realization of intra- and intermolecular interactions in polymer, which was proved by thermal analyses and hydrodynamic characteristics of coPAIs. This effect is discussed in the context of the effectiveness of intermolecular interactions between polymer chains containing carboxyl and hydroxyl functional groups.…”

Numerical Simulations of the Impact and Spreading of a Particulate Drop on a Solid Substrate by Hyun Jun Jeong, Wook Ryol Hwang, Chongyoup Kim

“…The Navier-Stokes equation is solved by a finite-element-based computational scheme that employs the level-set method for the accurate interface description between the drop fluid and air and a fictitious domain method for suspended particles to account for full hydrodynamic interaction. Focusing on the particle effect on droplet spreading and recoil behaviors, we report that suspended particles suppress the droplet oscillation and deformation, by investigating the drop deformations for various Reynolds numbers. …”

Research on Flow Regime Hydraulics of Sluice-Passing Flows in Reconstruction Design of Large Sluice in Meandering River Channels by ZHANG Zhouwen

“…Large sluices in meandering river channels have large sluice-passing flow rates and turbulent flow regimes during floods,and downstream energy dissipaters of the sluice cannot be easily repaired once they are damaged by erosion.Taking the reconstruction of the Jimei Sluice as a research project,this paper tries to solve the problem that how to make the reconstructed sluice avoid the large scour pit that has a size of 50 000 m² and a maximum depth of 23 m and is formed by the erosion of current downstream stilling pools.In addition,the paper uses the technical route of changing the layout of the sluice opening and the angle between the sluice axis and the river channel centerline and establishes a two-dimensional hydrodynamic mathematical model to analyze the water level,sluice-passing flow regimes,and erosion.The results of the comparison find that the angle between the sluice axis and the river channel centerline is 88° (rotating counterclockwise by 2°),and the full-depth sluice scheme is suitable.The research ideas and methods can provide a reference for similar projects.…”
