Special Issue Information

Dear Colleagues,

This Special Issue aims to showcase cutting-edge research, innovative methodologies, and practical applications in fire safety engineering, addressing both fundamental challenges and emerging technologies. We welcome contributions that advance the understanding of fire dynamics, improve fire prevention and mitigation strategies, and integrate interdisciplinary approaches to enhance structural and environmental resilience against fire hazards.

Topics of interest include, but are not limited to, the following:

  • Fire dynamics and combustion science: Modeling fire spread, flame behavior, and smoke management.
  • Structural fire safety: Fire-resistant materials, passive/active protection systems, and performance-based design.
  • Evacuation and human behavior: Crowd dynamics, risk communication, and smart evacuation systems.
  • Wildfire management: Detection, prediction, and mitigation strategies for urban and wildland interfaces.
  • Fire safety in smart cities: IoT-based monitoring, AI-driven risk assessment, and resilient infrastructure.
  • Regulatory frameworks and standards: Policy advancements, case studies, and lessons from fire incidents.

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. Applied Sciences is an international peer-reviewed open access semimonthly 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 incidence of fire accidents resulting from refrigerant leaking following the rupture of air conditioning condenser tubes has escalated in recent years. Corrosion from carboxylic acid is a primary cause in the rupture of copper tubes. The influence of lubricating oil and iron filings generated by the wear of air conditioning compressors on the corrosion of condenser copper tubes is rarely mentioned in the existing research. In order to simulate the environmental conditions inside the air conditioning unit, this study utilizes acetic acid vapor to corrode copper tubes and explores the effects of lubricating oil and iron powder on copper tube corrosion. The results demonstrate that copper corrosion follows a dendritic corrosion pattern, achieving a maximum depth of 51 μm after 28 days in 1% acetic acid vapor. A small amount of copper hydroxy acetate appears in the early stage. Copper hydroxy acetic and basic carbonate copper are converted into acetic acid copper hydrate as the acetic acid vapor increases over time. The ultimate products appear as turquoise-blue crystals. POE lubricant diminishes the corrosion rate by establishing an oil layer barrier that mitigates the volatilization of acetic acid. Iron powder preferentially reacts with acetic acid to initially protect the copper tube. The Fe3+ produced oxidizes the copper in acetic acid, hence the concentration of copper acetate rises, which facilitates the crystallization of copper acetate. Full article
