Aeroacoustic analysis based on FW–H analogy to predict low-frequency in-plane harmonic noise of a helicopter rotor in hover

open access: yesArchives of Mechanics, 2022
The integral formulation of the Ffowcs-Williams and Hawkings (FW–H) analogy, developed by Farassat (known as Farassat’s formulation 1A), is implemented to study the sound generation and propagation of rotating slender bodies.

Hydrogen production by the steam reforming of synthetic biogas in atmospheric-pressure microwave (915 MHz) plasma

open access: yesScientific Reports, 2023
This paper is a contribution to the development of microwave plasma-based technology aimed at efficient hydrogen (H2) production from a so-called synthetic biogas, considered a mixture of methane (CH4) and carbon dioxide (CO2), which can contain up to 70%

Barely visible impact damage identification in a 3D core sandwich structure

open access: yesComputer Assisted Methods in Engineering and Science, 2018
3D core sandwich structure (3DCSS) is a popular lightweight construction material in the automotive, aerospace and marine industries. However, barely visible low-speed impact-damage (BVLID) may occur in the 3DCSS due to foreign-object-impact that can ...

Hydrogen fuel production from CO2/CH4 mixture using a novel type of an atmospheric pressure microwave (2.45 GHz) plasma source

open access: yesScientific Reports
We report the use of microwave plasma for the production of hydrogen-enriched gas by converting a mixture of CO₂ and CH₄. A novel type of compact and simple in design, waveguide-based, atmospheric pressure plasma source is used.
