Investigation of the jet-flame interaction by large eddy simulation and proper decomposition method [PDF]

, 2019
Large eddy simulation (LES) results are presented for a premixed methane/air turbulent flame arising from a confined laboratory-scale single-nozzle burner. The jet issuing from an off-centered nozzle facilitates the development of a large-scale, dominant

MOF‐Derived Bi2WO6/MXene Ternary Heterojunction as a Highly Efficient Piezocatalyst for Ultrasound‐Driven Hydrogen Evolution and Oxygen Evolution Reaction

Small, EarlyView.
A Bi‐MOF‐derived Bi‐rich Bi2WO6/Bi3.84W0.16O6.24 ternary heterojunction with Ti2C MXene is developed as a highly efficient piezocatalyst. Ultrasound‐driven charge separation via a dual‐phase oxide and conductive MXene electron highway achieves an H2 evolution rate of 1450.1 µmol g−1h−1 through an unconventional •OH‐mediated pathway, with concurrent ...

Non-linearities in the thermoacoustic response of a premixed swirl burner

, 2009
PhDLean premixed combustion remains one of the simplest and most effective methods of reducing NOx emissions in industrial gas turbines. Lean premixed flames are however prone to an undesirable side effect known as combustion instability, reducing ...

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, EarlyView.
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.
