Special Issue Information

Dear Colleagues,

Medical ventilation has one primary aim, to transport gases up and down the human airway when a patient is unable to do this adequately for themselves. While this aim is simple, its implementation is not. The numerous physical factors include a vast range of time and length scales, the complex geometry, the presence of cilia, mucus layers and plugs, the inherent flexibility of the airway in the lower generations, and the fact that the flow must be reciprocating. These present a formidable challenge to understanding transport processes. On top of this, the gas transport needs to be achieved while avoiding further damage or trauma to a patient’s respiratory system. This has led to a series of ventilation strategies that vary in invasiveness—many of which rely on the manipulation of flows that are not well understood. There is vast potential, therefore, to optimize these strategies or invent new ones based on a greater understanding of the flow physics. This Special Issue of Fluids focuses on recent efforts to understand the flow processes that occur, and often need to be optimally exploited, during medical ventilation.

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.

The application of atomization technology is common in fields such as agriculture, cosmetics, environmental sciences, and medicine. Aerosolized drugs are administered using nebulizers to treat both pulmonary and nonpulmonary diseases. The characterization and measurement of nebulizers are of great significance in analyzing the performance and accuracy of the nebulizing system and the advancement of the technology. Nevertheless, the characterization of aerosols has been a long-standing challenge in scientific disciplines ranging from atmospheric physics to health sciences. The study of factors that influence nebulization has not been undertaken systematically using experimental techniques. Numerical modeling (NM) and computational fluid dynamics (CFD) can address such issues. This article provides a concise overview of the literature on the application of computational fluid dynamics to medical nebulizers and aerosol measurements. Full article
