Special Issue Information

Dear Colleagues,

This Special Issue of Aerospace is cooperating with the 21st IACM Computational Fluids Conference, which will take place on October 17–21 2021 in Hangzhou, China. The International Association for Computational Mechanics (IACM) has organized 20 conferences under the name FEF (International Conference on Finite Elements in Flow Problems) from 1972 to 2019. Starting in 2021, the conference series will be renamed to the IACM Computational Fluids Conference (CFC).

The conference aims at covering all aspects of Computational Fluid Dynamics (CFD), comprising topics from the most fundamental aspects to recent applications. It provides a world-wide forum for both academic researchers and industrial engineers to meet each other, to exchange information of all areas of fluid mechanics, and to discuss current and future advanced topics in the field.

The Special Issue, “Selected Papers from 21st IACM Computational Fluids Conference”, is designed to publish articles in the aerospace research field. The scope covers computational fluids problems, the fundamentals of mechanics and engineering science, flight vehicles, and propulsion and power systems. Some possible, but not limiting, keywords are listed below:

Fundamentals of Mechanics and Engineering Science

  • hydrodynamics;
  • aerodynamics;
  • aerothermodynamics;
  • plasma/non-equilibrium flow;
  • fluid-structure interaction;
  • aeroacoustics

Flight Vehicles

  • conceptual design and optimization;
  • aircraft;
  • helicopters;
  • missiles;
  • launchers;
  • high speed air breathing vehicles.

Propulsion and Power Systems

  • fundamentals of propulsion;
  • thermodynamics/thermochemistry;
  • reaction flow;
  • subsonic/supersonic combustion;
  • turbomachinery;
  • new propulsion systems.

Authors of contributions relating to the above key topics are welcome to submit extended versions of their conference work to this Special Issue for publication in our journal Aerospace.

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. Aerospace 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 2400 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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

In order to study the influence of streamwise forcing on the formation mechanism of liquid ligaments and droplets in the primary breakup process of liquid circular jet, the VOF interface capturing method-based direct numerical simulation was adopted, and a range of sinusoidal velocity disturbances with different frequencies were considered. The selected disturbance frequency range is 0–3000 kHz. This work analyzes the evolution process of the jet surface waves at different disturbance frequencies, and the coupling effect of the jet tip and liquid core on the overall spray field from overall structure, liquid ligament, and droplet formation. The results show that different disturbance frequencies affect the droplet shape distribution and size distribution in spray field. Current work provides guidance for the control of the thermoacoustic instability of the engine and design of the nozzle. Full article
