Special Issue Information

Dear Colleagues,

Atmospheric aerosols are subject to various processes that affect their concentration, distribution, chemical and physical properties and, as a consequence, their impact on climate, ecosystems, and human health. Transport and deposition phenomena involve physical and chemical processes that occur in the air and that directly affect the life cycle of aerosols in the atmosphere. This Special Issue aims to present the most recent and outstanding results on the transport, formation, dispersion, and kinetics processes that atmospheric aerosols undergo during their life cycle, as well as their impact on the environment and human health.
Topics of interest for the Special Issue include, but are not limited to:
- Modeling of aerosol formation, transport and deposition processes;
- Physical and chemical analysis of aerosols and their relationship with transformation processes;
- Impact of atmospheric aerosols on health, climate, and ecosystems;

  • Study of aerosol transformation processes, both indoor and outdoor;
  • Kinetic studies;
  • Applications.

and any other topic that is considered relevant and is framed within the objectives of this Special Issue.

The original research results related to the phenomena of transport, distribution, kinetics of aerosols, and their impact on both health and the environment are welcome contributions.

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. Atmosphere 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.

The deposition of ultrafine aerosols with a size range of 3–20 nm in a needle charger has been studied numerically by simulating the flow field and the particle trajectory. The calculation model explored the particle deposition in the needle charger without applied voltage for various particle diameters, flow rates, entrance radial positions and deposition axial distances. It is first quantitatively proposed that most of the particles are attached to the outer electrode wall instead of the needle electrode wall for different flow rates and particle diameters. It is found that the numerical results of the particle deposition of the needle charger are consistent with previous experimental data. Moreover, the results demonstrate that reducing the flow rate increases the particle deposition of the needle charger. The numerical models explain and quantify the particle deposition and its attachment position for the needle charger without applied voltage. Full article
