Mass entrainment rate of an ideal momentum turbulent round jet [PDF]

open access: yes, 2016
We propose a two-phase-fluid model for a full-cone turbulent round jet that describes its dynamics in a simple but comprehensive manner with only the apex angle of the cone being a disposable parameter.

Composite zeolite beta catalysts for catalytic hydrocracking of plastic waste to liquid fuels [PDF]

open access: yesMaterials for Renewable and Sustainable Energy, 2020
AbstractThe conversion of model waste plastic mixture into high-value liquid product was studied in the presence of hydrogen and composites of zeolite beta catalysts. For the sake of comparison, the conversion of actual waste plastic mixture and high-density polyethylene was also carried out.

Review on the Relationship Between Liquid Aerospace Fuel Composition and Their Physicochemical Properties [PDF]

open access: yesTransactions of Tianjin University, 2020
AbstractThe development of advanced air transportation has raised new demands for high-performance liquid hydrocarbon fuels. However, the measurement of fuel properties is time-consuming, cost-intensive, and limited to the operating conditions. The physicochemical properties of aerospace fuels are directly influenced by chemical composition.

Ionic Liquid Composite Polymer Electrolyte Membranes for the Unhumidified Intermediate Temperature Fuel Cell [PDF]

open access: yesECS Transactions, 2006
We synthesized novel composite polymer electrolyte membranes of [EMIm](FH)nF (n = 1.3 and 2.3) ionic liquids and measured their physical and electrochemical properties. The ionic conductivities of composite membrane (P(VdF-co-HFP):s-DFBP-HFDP: [EMIm](FH)2.3F = 1:0.3:1.75 in weight ratio) were up to 11.3 and 34.7 mS cm-1 at 25 and 130{degree sign}C,
