Posidonia oceanica Leaves as a Natural Filler for Poly(Butylene Succinate‐Co‐Adipate) Composites: Characterization and Biodegradation Assessment in Seawater

Journal of Vinyl and Additive Technology, Volume 32, Issue 4, Page 988-1005, July 2026.
This study shows that incorporating 5–10 wt.% Posidonia oceanica , with or without micro‐talc, in PBSA preserves thermal stability, modifying crystallization behavior, and maintains good filler dispersion and interfacial adhesion. Mechanical properties are moderately stiffened. ABSTRACT This study investigates the use of Posidonia oceanica (PO) leaves,

Effects of swirl on intermittency characteristics in turbulent non-premixed flames [PDF]

, 2012
Swirl effects on velocity, mixture fraction and temperature intermittency have been analysed for turbulent methane flames using LES. The LES solves the filtered governing equations on a structured Cartesian grid using a finite volume method, with ...

Energy‐Efficient Combustion Technologies and Burner Designs for Glass Melting Furnaces

International Journal of Applied Glass Science, Volume 17, Issue 3, July 2026.
ABSTRACT Glass production is one of the most energy‑intensive manufacturing processes, requiring furnace temperatures above 1600°C. These temperatures depend on burners that must balance thermal efficiency with emission reductions. This article reviews the development of combustion systems in glass furnaces, focusing on their impact on energy ...

Flow Field of Turbulent Premixed Combustion in a Cyclone-Jet Combustor

Journal of Thermal Science and Technology, 2007
The flow field in highly turbulent premixed combustion has been examined, using a cyclone-jet combustor. The shear-strain rate is obtained by PIV system. Results show that, in combustion field, mean axial velocity does not decay along center axis and RMS
