Reduction of Flow-Induced Sound of Airframe, Vehicle, and Engine at Component Level

Dear Colleagues,

Aircraft noise is a significant nuisance for communities surrounding airports. It is not surprising that airport expansion plans are met with increasing noise regulations driven by the community’s fear of increasing noise pollution. Depending on the flight condition of an aircraft, the dominant noise sources can be identified as engine or airframe noise (e.g., during take-off or landing). One of the challenges in this area is a solution for the potential conflict between the growth of air transportation systems on one hand and the required noise reduction on the other hand. In the majority of cases, aircraft noise is an aeroacoustic phenomenon (i.e., flow-induced noise). Some examples of airframe noise are noise of landing gear, flap side-edge or trailing edge noise. In the last few years, much research has been conducted on the mechanisms of such noise and the potential means of reducing the noise created by such components.

In light of the above, this Special Issue of Fluids is dedicated to the study of the reduction of airframe and engine noise at the component level. Submissions are now being accepted, and the deadline is September 1^st, 2021. The scope of this Special Issue includes the noise mechanisms and specific noise reduction, ranging from component level to overall aircraft noise assessment. Original research articles, reviews, meta-analyses and methodological reports that involve the study of turbulent sound sources in relation to noise reduction in the context of aircraft noise, automotive noise and wind energy noise will be accepted.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Fluids is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
