Special Issue Information
Dear Colleagues,
Across fire science and fire-related technologies, many critical scenarios involve high-temperature, low-oxygen, highly diluted conditions, from underventilated compartment fires and industrial heating to emerging hydrogen and ammonia systems. In these regimes, heat release can become spatially distributed rather than flame-front-dominated. Moderate or Intense Low-Oxygen Dilution (MILD), flameless combustion/HiTAC, and colorless distributed combustion (CDC) demonstrate uniform temperature fields, stable operation over wide equivalence ratios, and ultra-low NOx/soot values. Understanding and exploiting distributed reaction zones can inform safer, cleaner fire-related technologies, improve industrial furnace/kiln performance, and support fuel transitions. Cross-fertilization with fire dynamics (ignition, transition, extinction, radiative exchange, ventilation effects) and modern measurement/analytics can accelerate both scientific understanding and real-world impacts. We lack an integrated, fire-centric view of distributed combustion that couples validated models with high-fidelity measurements under high-T/low-O₂, quantifies uncertainty, and translates fundamentals to design, control, and safety guidelines. For this Special Issue, we invite the submission of rigorous studies that fill in these gaps and provide actionable knowledge, benchmarks, and datasets for the fire community.
Topics of interest include (but are not limited to) the following:
- Fundamentals of MILD/HiTAC/CDC and ignition/transition/extinction in diluted, preheated oxidizers;
- Fire dynamics links: underventilated/vent-limited conditions, radiation–mixing interplay, and stability/flashback;
- Diagnostics and thermal metrology: temperature/emissivity, IR/hyperspectral, chemiluminescence/PLIF, PIV/schlieren, calibration, and uncertainty;
- AI-driven analysis: data assimilation, reduced-order/surrogate models, super-resolution, sensor fusion, and anomaly detection;
- Modeling and validation: LES/DNS/RANS, detailed/reduced kinetics, radiation, UQ/reproducibility, and open datasets;
- Fuels and emissions: hydrogen, ammonia, biofuels, blends, ultra-low-NOx/CO/soot strategies, and safety implications;
- Applications: industrial furnaces/ovens/kilns and gas turbine-relevant systems, control/retrofit case studies, and TEA/LCA where relevant.

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. Fire 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.
