Research on Heat Transfer Enhancement of Spiral Grooved Tube Heat Exchangers Based on CFD and Artificial Intelligence

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Driven by the energy crisis and carbon neutrality goals, high‐efficiency heat exchange equipment has become a core demand in the industrial sector. The spiral grooved double‐pipe heat exchanger exhibits significant heat transfer enhancement advantages, yet it requires balancing heat transfer efficiency and pressure loss.

Linear Viscoelastic Behavior of n‐Alkane Diluted Polyethylene Melts: Sorption, Desorption, and Oscillatory Rheometry

open access: yesJournal of Applied Polymer Science, EarlyView.
This study systematically maps polyolefin dilution dynamics using a homologous series of n‐alkanes. Integrating gravimetric sorption, subsequent controlled desorption, and oscillatory rheometry establishes a precise framework to analyze reduction in viscosity at least for polymer diluent mixtures with polymer concentration > 35% and diluent ...

Long‐Time Thermal Aging of Perfluoroalkoxy Polymers for Electrical Insulation: Structural and Physical Properties Evolutions

open access: yesJournal of Applied Polymer Science, EarlyView.
This work focuses on the investigation of the influence of a long‐time exposition to accelerated thermal aging on the physicochemical structure and properties of PFA. Results show a decrease in the melting temperature and crystal ratio due to chemical aging.

Valorization of Post‐Consumer Waste From Metallized Flexible Packaging and Industrial EPM Waste: Development of Sustainable Composites

open access: yesJournal of Applied Polymer Science, EarlyView.
Post‐consumer metallized flexible packaging waste and industrial EPM waste are transformed into sustainable composites through mechanical recycling. The incorporation of 30 wt% EPM provides the most favorable balance between stiffness, ductility, and impact resistance, achieving 53.36 kJ/m2.

Fibrillisation and Mechanical Properties of Plasma‐Treated Modification LDPE/PA6 Microfibrillar Composites

open access: yesJournal of Applied Polymer Science, EarlyView.
Plasma treatment enhances interfacial adhesion between LDPE/PA6 via carbonyl group formation. PA6 droplet size heterogeneity reduced to ~850 nm after plasma treatment. Drawing at 160°C produces highly oriented microfibrils with faster throughput. Plasma‐treated MFCs show up to 500% tensile strength increase and 18% higher stiffness.
